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:
