> *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.
