Subject [jira] Commented: (HBASE-3426) Allowing HRegionServer extensions to register interfaces for HBaseRPCMetrics
Date Fri, 07 Jan 2011 00:06:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12978584#action_12978584

Gary Helmling commented on HBASE-3426:
--------------------------------------

Hi James, I already committed a change for this as HBASE-3405 to 0.90 and trunk.  If there
are any issues with the interface there, we can address them here.

Otherwise we should close this as a dupe?

> HBaseRpcMetrics is now logging a WARN message every time it encounters an
> unregistered RPC method.
> In my case I now get huge log files filled with these warnings because the
> hbase-trx transactional extension of HBase uses a subclass of HRegionServer
> that adds new interface methods.
> It's easy enough to tell log4j to ignore HBaseRpcMetrics output.
> However, it would be nice if the Server/HRegionServer HBaseRpcMetrics
> mechanism was more extensible so I could pass down new interfaces or grab
> the HBaseRpcMetrics from the HBaseRPC object to add interfaces from up
> top...
