Junping Du commented on YARN-4913:
----------------------------------
bq. yarn logs > $targetFile produces a single file that appends all the
individual container logs. This requires (clumsy | complex) parsing to split
the files apart if you are looking for specific task or app-specific logs.
Writing to a directory will preserve the distinct files easily and also lend
itself to archiving.
+1. I experienced this pain recently on a application with 16G+ application log
which is almost unreadable. Split this into files could be very useful in this
case.
> Yarn logs should take a -out option to write to a directory
