You will not receive any benefits of a long rest
This includes Hit Die refresh, Hit Point recovery, spell slots, abilities that refresh on a long rest, etc.
Basically, while you won't suffer the negative effects of skipping a long rest, you also don't enjoy any of the benefits of having taken one.
It's a subtle nod to the fluff
From page 22 of the Eberron Campaign Setting:
Older warforged tend to be fighters or barbarians. The more recently created warforged, especially those less than five years old, are more inclined to try different class options.
Aarren d'Cannith created the first warforged 33 years before the present. They were mass-produced ...
The Direct Answer
The direct answer is yes, the DM can override racial traits and absolutely anything else they want to override.
Your Specific Situation
This would be an odd thing to override. First, most campaigns don't make a big issue out of food and water. They are often assumed to be adequately available so that it doesn't become much of a mechanical ...
See The D&D Adventurers League Player & DM Pack which includes player's guides for the Forgotten Realms campaign (including the Season 8 Waterdeep Dragon Heist & Dungeon of the Mad Mage and Season 4's Ravenloft material, among others) and the stand-alone Eberron Campaign.
Each has a section on Character Creation which includes "...
House Cannith perfected modern, sentient warforged in 965 YK. The Treaty of Thronehold, which ended the Last War and required House Cannith to destroy the Creation Forges, was in 996 YK. All (legal) warforged were produced during this 31-year period. The combatants during this timeframe were:

Dragonborn of Bahamut
The traditional (cheesy) approach is to use the dragonborn template from Races of the Dragon. Dragonborn is an LA +0 acquired template, not inherited, and can apply to warforged. It replaces most racial traits with those of dragonborn. Dragonborn are Humanoid (dragonblood).
The fact that dragonborn is an acquired template is what’s ...
Yes, Warforged Barbarians suffer no ill-effects after raging.
From Races of Eberron, page 23:
As a warforged, your Constitution bonus allows you to rage longer, your immunity to fatigue means you suffer no ill effect when your rage ends, ...
As of 5e's published release and the Unearthed Arcana article, Warforged are treated no differently than PCs of other races.
Since it does not mention any healing exceptions for warforged in the Unearthed Arcana article that introduces them to 5e; they should have any and all healing effects work on them as per usual.
2018 update (thanks @Trevel)
It doesn't say it counts as armor or natural armor or anything, so it doesn't. It's just 1 AC on top of everything else, to emphasize the sturdiness of Warforged. It should stack with everything and prohibit nothing.
To support this, note that the Warforged trait provides a bonus to AC, rather than setting it to a number, as armor is wont to do. The ...
Warforged can have gender identities, and many warforged go out of their way to experience “life” in general. For most, this is limited to things like trying fine food and drink, even though it serves no biological purpose for them, but many do more. For example, consider the tracker mask warforged component from Races of Eberron, which grants a warforged ...
"Warforged, roll out!"
The Integrated Tool feature says (emphasis mine):
Choose a tool you're proficient with. It becomes integrated into your body, and you double your proficiency bonus for any ability checks you make with it. You must have your hands free to use this tool.
So RAW this means any tool you are proficient with is eligible. So the ...
The AC is the Beast's AC
Your game statistics are replaced by the statistics of the beast, but
you retain your alignment, personality, and Intelligence, Wisdom, and
What you retain does not say "you retain your armor class" or but rather: alignment, personality, and Intelligence, Wisdom and Charisma scores. (See also the Q&A ...
Composite Plating and Heavy Plating are intended to count as armor.
Keith Baker, original creator of Eberron and lead designer for the Wayfinder's Guide to Eberron, addresses this question (and many others) in the WGtE FAQ on his website:
Does the Warforged Heavy Plating Integrated Protection work with the Fighter’s Defense Fighting Style? Unclear on if (...
The specific beats general concept does not seem to help here. We have two specific rules that override the general rule: A warforged takes an hour to integrate or remove armor, and Cast-Off Armor can be doffed as an action.
As in many cases of conflicting special rules, the fallback position is simply to ask the DM how it's going to work at your table. ...
Unfortunately, you're going to have to ask DNDguide
While discovering 3rd party content can create new and interesting opportunities, there are issues that arise that only the content creator can answer - and this is one of them.
The race itself is not mechanically described with the standard 5e terminology. The use of the term focus ...
Outside of mechanics, talk to your DM/party about this
As others have noted, there are mechanical ways to fluff existing options to this sort of skinwalking, but I wanted to point out another issue: table viability of the strategy.
Whether or not this is do-able is almost secondary to this issue,. I would heavily recommend that you discuss your plans with ...
4e doesn’t have rules for limb-loss and therefore does not have rules for what to do about it
Since the game rules do not include any way for you to lose limbs, they also do not include any solutions to lost limbs. If you houserule in limb loss, which I strongly recommend against, you also have to houserule any solutions. There was a similar situation in 3.5;...
It's canonically ambiguous.
Like many of the big mysteries in Eberron, this question is left to the DM to decide. This type of intentional moral and cosmological ambiguity is a big part of the theme of the Eberron setting.
The people of Khorvaire consider the question of do warforged have souls? to be unsolved and controversial. The Eberron Races Unearthed ...
Yes, you have to choose one
You have to
Choose a tool you're proficient with
That doesn’t let you choose a type of tool, you have to choose a specific singular tool from the type. “Vehicles” isn’t singular any more than “musical instruments” is singular. “A rowboat” or “a bagpipe” are singular options.
Your integrated tool is the specific one ...
Yes, Composite Plating and Heavy Plating count as "armor".
It would certainly be helpful if it said, "composite plating and heavy plating count as armor for you", that would make it very clear, but it doesn't say that.
However as you noted, it is heavily implied in the Mode column. I think it goes beyond heavily implying, it's telling ...
RAW, they don't stack
From the basic rules on proficiency bonus (emphasis mine):
Your proficiency bonus can’t be added to a single die roll or other number more than once.
In this case, the number would be your AC for this attack. So, a warforged benefiting from Integrated Protection and using one of the modes that already add your proficiency bonus to ...
Warforged don’t need to eat or drink
As per the book Eberron: Rising From the Last War, the official fifth edition source for Eberron, Warforged have the Constructed Resilience trait, which confers several benefits including:
• You don’t need to eat, drink, or breathe.
The description makes no mention of them requiring any other form of sustenance, ...
Yes: it gives the warforged a free tool integrated into its body, and expertise (double proficiency) with that tool
It's pretty clearly stated in the Envoy warforged's Integrated Tool feature description:
Choose one tool you’re proficient with. This tool is integrated into your body, and you double your proficiency bonus for any ability checks you make with ...
It's hard to say
In the Wayfinder's Guide to Eberron, the specific subraces have guidance on build and weight difference. That being said, only the Juggernaut subrace lists a weight ("up to 450 pounds") out of the three subraces provided in the book. The Skirmisher mentions that they are "lean and designed for speed."
The only other weight references I ...
It is canonically undefined
In published 5e lore, the only mention of a warforged soul is in the introduction to the race:
“Pierce was built by design, while you were built by accident,” Lakashtai said. “The soul is what matters, not the shape of the vessel.”
“What makes you think he has a soul?” Gerrion said.
“What makes you think you do?”
— Keith Baker, ...
They can suffer exhaustion, just not due to lack of rest.
"Exhaustion due to lack of rest" is carefully qualified. There are creatures that are immune to "exhaustion" (such as the Ghost). This is different. Lack of rest is just one of many ways to become exhausted; there's also starvation (though Warforged are immune to that too), exposure to extreme ...
Ask your DM, if he/she allows UA
Faerûn and Ravenloft are the only 5e settings with official published material to date, and there are no warforged native to Faerun or Ravenloft. Your DM might choose the Eberron setting, and if they do, they probably will use the related Unearthed Arcana materials, where you can find the warforged race description. (You ...
Yes: The GM is the final arbiter of the campaign, subject to the players just getting up and leaving him without a game to arbitrate. Moreover, GMs often override specific rules from the rulebooks in order to set a certain desired aesthetic or produce some certain effect.
I myself have overridden race bonuses in games before, although the ...
It's safe from exhaustion, most likely
First of all, going without sleep causing exhaustion is already a variant rule of sorts, introduced in Xanathar's Guide to Everything (p. 78), which specifically states that you "can use these rules if you want to account for sleep deprivation". I assume they removed the "you don't suffer exhaustion" ...
It does not get fatigued
Well, technically what happens is the rage tries to apply the condition and then the barbarian ignores it, but "immunity" is pretty explicit - the warforged cannot suffer the effects of fatigue.
