Subject [jira] [Commented] (HBASE-5589) Add of the offline call to the Master Interface
Date Tue, 20 Mar 2012 23:38:40 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5589?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13233947#comment-13233947
] 

Jonathan Hsieh commented on HBASE-5589:
---------------------------------------

And the calling side encodes method names as part of a Writable Invocation so the interface
it seems that order in the interface doesn't matter. 

https://github.com/apache/hbase/blob/trunk/src/main/java/org/apache/hadoop/hbase/ipc/Invocation.java#L99

This looks to be the case in 0.90 as well. 
https://github.com/apache/hbase/blob/0.90/src/main/java/org/apache/hadoop/hbase/ipc/HBaseRPC.java#L105

Here's where I need advice.  Should bump the protocol version in trunk/0.96/0.94 (HMasterInterface)?
What should I do about the protocol version number released version to maintain compatibility
-- specifically 0.90.x (HBaseRPCProtocolVersion) or 0.92.x (HMasterInterface)?  Keep it the
same?

> Hbck from HBASE-5128 requires an offline method on the master to properly cleanup state
during certain assignment repair operations.  This will this method will be added to recent
and older versions of HBase.
