[jira] [Created] (HBASE-14517) Show regionserver's version in
master status page
Liu Shaohui created HBASE-14517:
-----------------------------------
Summary: Show regionserver's version in master status page
Key: HBASE-14517
URL: https://issues.apache.org/jira/browse/HBASE-14517
Project: HBase
Issue Type: Improvement
Components: monitoring
Reporter: Liu Shaohui
Assignee: Liu Shaohui
Priority: Minor
In production env, regionservers may be removed from the cluster for hardware problems and rejoined the cluster after the repair. There is a potential risk that the version of rejoined regionserver may diff from others because the cluster has been upgraded through many versions.
To solve this, we can show the all regionservers' version in the server list of master's status page, and highlight the regionserver when its version is different from the master's version, similar to HDFS-3245
Suggestions are welcome~
