Akira AJISAKA commented on MAPREDUCE-6579:
------------------------------------------
bq. One approach i can think of is checking the status of job in the MR client
side and only if its failed we can fetch and return the diagnosis message from
yarn else we can return empty string. This will ensure the compatability is not
broken if any client application is checking the failure message with out
checking the job status.
Sounds good. I'll update the patch. I'll update and the summary of this issue
as well.
