Bikas Saha updated TEZ-2394:
----------------------------
Attachment: TEZ-2394.1.patch
There is a subtle race condition that may cause this. It does not reveal a bug
but it shows that the Precondition check was not correct. Since this is a rare
race condition between threads, I have no way to test it. So instead I have
added other Preconditions and error reporting to shed more light in case the
fix in the patch is not correct. The fix in this patch is to remove the
Preconditions since its not valid. Explanation in the comments in the code.
[~hitesh] Please review.
