Subject [jira] [Commented] (HBASE-4048) [Coprocessors] Support configuration of coprocessor at load time
Date Sat, 16 Jul 2011 21:40:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4048?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13066540#comment-13066540
] 

Jason Rutherglen commented on HBASE-4048:
-----------------------------------------

Is there documentation on how to use this API?  It looks like the main entry point is represented
in this sample code?

{code}
htd.setValue("COPROCESSOR$2", jarFileOnHDFS2.toString() + "|" + cpName2 +
+"|" + Coprocessor.PRIORITY_USER + "|k1=v1,k2=v2,k3=v3");
{code}

Where pipe is used as a separator?  Looks like pipe is required?

> Users should be able to pass configuration options to coprocessors. These options should
be applied at load time.
> - For system coprocessors, just use the configuration of the container. 
> - Extend table coprocessor load specification to allow arbitrary key-value pairs at the
end (<key>=<value>{,}).
