Subject [jira] [Commented] (PHOENIX-5252) Add job priority option to UpdateStatisticsTool
Date Tue, 23 Apr 2019 23:14:00 GMT

Chinmay Kulkarni commented on PHOENIX-5252:
-------------------------------------------

[~yanxinyi] Thanks for the contribution! Committed to master and 4.x-HBase-1.4 branches. According
to [~karanmehta93]'s comment on PHOENIX-4009 where he is referring to the UpdateStatisticsTool, 

"The patch requires hbase-metrics and hbase-metrics-api modules which are not present in HBase
versions < 1.4, hence the patch cannot be ported."

So, not porting to other branches.

> This Jira adds a new command line option that allows users to specify the job priority
to the tool. 
> The current implementation doesn't support the MR job priority, and it might limit the
usecase. For instance, we have 10 running jobs in a queue, and we get a new urgent MR job.
Instead of deleting all currently running jobs, inserting a high priority job could solve
this problem.
