Subject Re: [VOTE] Release Apache Hadoop 2.9.0 (RC0)
Date Tue, 07 Nov 2017 07:17:18 GMT
Thanks Subru/Arun for the great work!

Downloaded source and built from it. Deployed RM HA non-secured cluster
along with new YARN UI and ATSv2.

I am facing basic RM HA switch issue after first time successful start. *Can
anyone else is facing this issue?*

When RM is switched from ACTIVE to STANDBY to ACTIVE, RM never switch to
active successfully. Exception trace I see from the log is

2017-11-07 12:35:56,540 WARN org.apache.hadoop.ha.ActiveStandbyElector:
