@Irfan

When the alert was getting triggered that time did you check the Region Server logs ?
The GC activities of region server?


Following are the possible cause of the mentioned alert:

1. Misconfiguration or less-than-ideal configuration caused the RegionServers to crash.

2. Cascading failures brought on by some workload caused the RegionServers to crash.

3. The RegionServers shut themselves own because there were problems in the dependent services, ZooKeeper or HDFS.

4. GC paused the RegionServer for too long and the RegionServers lost contact with ZooKeeper.
