Siddharth Seth commented on TEZ-2859:
-------------------------------------
Looks good. [~rajesh.balamohan] - to ensure I understand this correctly. The
real merge thread is interrupted by the 'Interrupting Thread'. This doesn't
show up as an exception in the main test thread - and instead causes the merge
to exit early. Since the merge has exited early - the count should be > 1. With
the patch, if the merge happens fast - the last closeOnDiskFile will be
interrupted, and the final cleanup of structures won't happen ?
