Description

bin/hbase VersionInfo is a great existing utility to provide version info about Hbase jar files. Unfortunately, there is no way to currently get this information for the running process. For this jira, add an easy/quick way to see verify the rev of the running jar.

We got recently bit internally because our running jar was a different version from the jar that we had recently pushed and caused havoc on our cluster. This problem is more important to fix now that we have rolling upgrades and will regularly have cluster scenarios with mixed-version RSs.
