-------------------------------------------------
Is this a Trafodion issue or a vendor issue? (AdvEnt2.3 seems to be a vendor
product.)
> Prepare query returns 2006 internal error

> 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:
