Weiwei Yang commented on YARN-6177:
-----------------------------------
Fixed the minor checkstyle issue in v3 patch. And attached some sample job log
files to help to explain the issue and the fix:
# Without the patch, submit a spark2 job to yarn fails pretty quickly with
NoClassDefFound error, see output in [^spark2-job-output-before.out]
# With this patch, submit the job again, it still fails with the same error,
but with additional clearer error messages, see output in
[^spark2-job-output-after.out]
# Apply the suggestion given in the error message, set best-effort to true to
tolerant this error, then submit the job again and the job succeed, see output
in [^spark2-job-output-after-besteffort.out]
> Yarn client should exit with an informative error message if an incompatible
> Jersey library is used at client
