-------------------------------------
Summary: Prepare query returns 2006 internal error
Key: TRAFODION-2988
URL: https://issues.apache.org/jira/browse/TRAFODION-2988
Project: Apache Trafodion
Issue Type: Bug
Reporter: chenyunren
This query preparation comes from an existing regression test and it used to
work fine. Now it returns a 2006 internal error at mdam.cpp:1611 when the CQD
HBASE_HASH2_PARTITIONING is turned off.
This is seen on the AdvEnt2.3 20171016 daily build:
