Vinod Kumar Vavilapalli updated HADOOP-3464:
--------------------------------------------
Attachment: HADOOP-3464.1
Attaching a new patch
- Fixes the problem of transferring hodring error msgs to hod client.
- Fixes a minor problem in the earlier patch - now print ringmaster error msgs
both when return status is 5 or 6.
This patch needs some cleanup - removing extraneous debug statements, making
log statements better, make better how data(error msgs) are transferred from
hodrings to ringmaster and then to hod client, and even perhaps clean up of api.
Extra effort would be changing the error messages themselves - this patch only
addresses the issue of bringing them to hod client, that is all. That anyway
should be part of new jira issues.
> [HOD] HOD can improve error messages by reporting failures on compute nodes
> back to hod client
