Subject [jira] [Updated] (HBASE-17346) Add coprocessor service support
Date Wed, 18 Jan 2017 13:56:27 GMT

     [ https://issues.apache.org/jira/browse/HBASE-17346?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Duo Zhang updated HBASE-17346:
    Attachment: HBASE-17346.patch

Add coprocesorService methods in RawAsyncTable. And implement an AsyncAggregationClient which
only has a max method for now.

As we need the RpcController to pass exceptions for asynchronous stub, which means we need
a customized RpcController implementation when calling the methods of coprocessor stub, I
removed the coprocessService method which returns an RpcChannel.

Batch coprocessorService has not been implemented yet, just put the patch here to collect
some feedbacks. Will add full support later(maybe in new issues?)
