Rushabh S Shah commented on HDFS-11711:
---------------------------------------
[~brahma]: the latest patch looks good.
There is one checkstyle warning (in branch-2 patch) and 1 more warning (in
trunk patch) that needs to be addressed. I wouldn't submit a new patch and
waste build resources for that.
The committer can fix it while checking in.
I verified the tests (that failed from branch-2 patch) passes locally for me.
[~brahma]: Can you verify test failures from trunk patch are not related to
your patch ?
Other than that, +1 (non-binding) from me.
Thanks !

> *Seen the following scenario in one of our customer environment*
> * while jobclient writing {{"job.xml"}} there are pipeline failures and
> written to only one DN.
> * when mapper reading the {{"job.xml"}}, DN got {{"Too many open files"}} (as
> system exceed limit) and block got deleted. Hence mapper failed to read and
> job got failed.
