It would have taken me a while to notice but at the base of my list of regionservers, there was a helpful ' 9 nodes with inconsistent version'.. Nice. Thanks. > 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 > Fix For: 2.0.0, 1.2.0, 1.3.0 > > Attachments: HBASE-14517-v1.diff, HBASE-14517-v1.patch, HBASE-14517-v2.patch > > > 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~ -- This message was sent by Atlassian JIRA (v6.3.4#6332)
