Subject [jira] [Created] (DRILL-5326) Unexpected/unhandled MinorType value GENERIC_OBJECT
Date Tue, 07 Mar 2017 20:01:37 GMT
Vitalii Diravka created DRILL-5326:

             Summary: Unexpected/unhandled MinorType value GENERIC_OBJECT
                 Key: DRILL-5326
                 URL: https://issues.apache.org/jira/browse/DRILL-5326
             Project: Apache Drill
          Issue Type: Bug
          Components: Metadata
    Affects Versions: 1.10.0
            Reporter: Vitalii Diravka
            Assignee: Vitalii Diravka
            Priority: Blocker
             Fix For: 1.10.0

In DRILL-5301 a new SERVER_META rpc call was introduced. The server will support this method
only from 1.10.0 drill version. For drill 1.10.0-SNAPHOT it is disabled. 
When I enabled this method (by way of upgrading drill version to 1.10.0 or 1.11.0-SNAPSHOT)
I found the following exception:
java.lang.AssertionError: Unexpected/unhandled MinorType value GENERIC_OBJECT
It appears in several tests (for example in DatabaseMetadataTest#testNullsAreSortedMethodsSaySortedHigh).
The reason of it is "GENERIC_OBJECT" RPC-/protobuf-level type is appeared in the ServerMetadata#ConvertSupportList.
(Supporting of GENERIC_OBJECT was added in DRILL-1126).

The proposed solution is to add the appropriate "JAVA_OBJECT" sql type name for this "GENERIC_OBJECT"
RPC-/protobuf-level data type.
