Devaraj K updated MAPREDUCE-6773:
---------------------------------
Affects Version/s: MR-6749
Status: Patch Available (was: Open)
I have updated the patch with changes, and will update with these once we have
conclusion about the above and below points.
bq. if we plan to use MR_AM_CONTAINER_REUSE_MAX_MAPTASKCONTAINERS (also reduce
one), then we need to rename the prefix from yarn.app.mapreduce.am to
yarn.app.mapreduce & mapred-default.xml needs to be updated
We have already renamed these configs as part of MAPREDUCE-6772 and we are just
referring the constants from MRJobConfig.java. Is there anything else you are
referring here?
bq. JOB_CONTAINER_COMPLETED, is it related to this patch ? should it be in
MAPREDUCE-6784? seems like not used anywhere in the current patch.
I removed this as part of this patch, will add it with MAPREDUCE-6784 or other
jira.
bq. ContainerRequestorEvent has almost similar naming to that of
ContainerRequestEvent, further was wondering whether we can rename it to
ContainerReUseRequestEvent, as its only used by RMContainerReUseRequestor.
Currently we are referring ContainerRequestorEvent from RMContainerRequestor
and RMContainerReuseRequestor. I think the name RMContainerReUseRequestor would
not match properly for RMContainerRequestor. Any suggestions?
