[jira] [Created] (KYLIN-1645) Exception inside coprocessor should report back to the query thread

liyang created KYLIN-1645:
-----------------------------

             Summary: Exception inside coprocessor should report back to the query thread
                 Key: KYLIN-1645
                 URL: https://issues.apache.org/jira/browse/KYLIN-1645
             Project: Kylin
          Issue Type: Bug
            Reporter: liyang
            Assignee: hongbin ma


Currently, exception inside coprocessor is logged at query side, but in a separate thread. E.g.

2016-05-02 23:19:07,130 ERROR [pool-3-thread-23] v2.CubeHBaseEndpointRPC:110 : Caught exception in thread pool-3-thread-23: 
java.lang.RuntimeException: <sub-thread for GTScanRequest 7d354973> Error when visiting cubes by endpoint

The problem is the exception does not notify the main query thread, which will wait to timeout and throw out "Timeout visiting cube!" to client. Very misleading.
