Re: NM status during RM failover

[Dong Ye]

Hi, All:

How to reduce RM fail over because it introduces disturbances to current
workload. The failover is mainly because of JVM pause (around 6 seconds)and
high CPU usage.

Thanks.
Have a nice day!

NM status during RM failover

[Dong Ye]

Hi, All:

  I have a question, in the high availability resource manager
scenario, how does the states of NodeManagers change if a new leader RM is
elected? We observe a drop of NumActiveNodes metric when fails over on a
new RM. Is that normal? Any documentation explains how the NM states will
change? RM version is 2.8.5.

Thanks.
Have a nice day!
