Subject Re: [VOTE] Release Apache Hadoop 2.7.4 (RC0)
Date Fri, 04 Aug 2017 18:19:48 GMT
Hi Wei-Chi,

There is bunch of performance jiras in Hadoop.
This one is not marked as blocker and seems to be hard to reproduce.
And I see that you are still discussing the problem and the solution with
Daryn in the jira.
I don't think it should block the release.
If this or anything else will prove to be a serious problem we can follow
up with a maintenance release containing hotfixes only.

Thanks,
--Konst
