Jonathan Eagles commented on TEZ-3813:
--------------------------------------
[~samirkhan], Can we try removing the MemoryFetchedInput#size member. That
would allow us to move us one 8 bytes boundary more for this object. We will
have to avoid the null pointer exception in
SimpleFetchedInputAllocator#cleanup. Perhaps just moving byteArray = null;
below the notifyFreedResource call?

> Same as TEZ-3752 for the unordered case. MemoryFetchedInput has a
> BoundedByteArrayOutputStream that is not used (only the underlying byte[] is
> used).
