Subject [jira] [Updated] (HBASE-13216) Add version info in RPC connection header
Date Thu, 30 Apr 2015 19:50:07 GMT

     [ https://issues.apache.org/jira/browse/HBASE-13216?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Purtell updated HBASE-13216:
-----------------------------------
    Fix Version/s: 0.98.13

I picked this back to 0.98 too. It's a safe compatible change. Useful as described for identifying
remaining versions that need update in a staged/partial upgrade. While doing this I noticed
we are not calculating a source checksum in 0.98 for the version annotation. The annotation
is marked private and it's user, VersionInfo, is marked evolving, so I've added this to 0.98
as well.

> In the operation of a cluster, we usually want to know which clients are using the HBase
client with critical bugs or too old version we will not support in future.
> By adding version info in RPC connection header, we can get these informations from audit
log and promote them upgrade before a deadline.
> Discussions and suggestions are welcomed. Thanks.
