Rohith Sharma K S commented on YARN-8155:
-----------------------------------------

TimelineServiceV2Publisher printing exception message which could fill up logs very quickly.
Probably we should log exception only in debug log but not for info logs.

> We see that NM logs are filled with larger stack trace of NotFoundException if collector
is removed from one of the NM and other NMs are still publishing the entities.
>  
> This Jira is to improve the logging in NM so that we log with informative message.
