--------------------------------------
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:
{code}
java.lang.AssertionError: Unexpected/unhandled MinorType value GENERIC_OBJECT
{code}
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.
