Ayush Saxena commented on HDFS-14669:
-------------------------------------
[~iamgd67] I am not sure with the fix, I guess the correct fix should be to
ensure that the condition being waited for gets met, rather than removing it.
Do you have any way as to reproduce this issue, which leads to the same
exception message. i.e stuck in the waitFor!!!
Well HDFS-12319 added the test, check there or try with people involved there.
They would be the best ones to help here!!!
