Thanks for the response, Anoop. On hbase 94.3 - I tried the code given in this API example documentation http://hbase.apache.org/0.94/apidocs/org/apache/hadoop/hbase/coprocessor/example/BulkDeleteProtocol.html
And it was throwing Tue Aug 13 09:26:55 PDT 2013, org.apache.hadoop.hbase.ipc.ExecRPCInvoker$1@2a862a86, org.apache.hadoop.ipc.RemoteException:org.apache.hadoop.hbase.ipc.HBaseRPC$UnknownProtocolException:org.apache.hadoop.hbase.ipc.HBaseRPC$UnknownProtocolException: No matching handler for protocol org.apache.hadoop.hbase.coprocessor.example.BulkDeleteProtocol in region hb1,,1376384424873.766e3ebcec45cbbbabfaee06012866a1. at org.apache.hadoop.hbase.regionserver.HRegion.exec(HRegion.java:5070) at org.apache.hadoop.hbase.regionserver.HRegionServer.execCoprocessor(HRegionServer.java:3632) Realize now that I also needed to explicitly load the coprocessor implementation class (BulkDeleteEndpoint) even though its a system coprocessor through hbase-site.xml.. .https://blogs.apache.org/hbase/entry/coprocessor_introduction.. It works now.
