Subject [jira] [Created] (HBASE-14517) Show regionserver's version in master status page
Date Wed, 30 Sep 2015 05:31:04 GMT
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~
