Rohini Palaniswamy commented on OOZIE-2329:
-------------------------------------------
bq. -1 TESTS - patch does not compile, cannot run testcases
Can you check?
Just one minor comment. Move System.out.println("tag id : " + tag); after the
if block, else it is going to print tag id : null, everytime when yarn restart
handling is disabled.
{code}
+ System.out.println("tag id : " + tag);
+ if (tag == null) {
+ System.out.print("Could not find Yarn tags property " +
CHILD_MAPREDUCE_JOB_TAGS);
+ return childYarnJobs;
+ }
{code}
> Make handling yarn restarts configurable

> For a cluster with lot of RUNNING jobs, this overwhelms RM causing lot of
> blocked threads as it does ACL check on each application before applying the
> filter tag and that is inside a synchronized block. Hadoop team is looking
> at doing the filtering first outside synchronized block to limit the number
> of applications for which ACL check needs to be done reducing time spent in
> synchronized block.
