Subject [GitHub] trafodion pull request #1525: [TRAFODION-3028] Support CONTROL QUERY SHAPE (...

    [TRAFODION-3028] Support CONTROL QUERY SHAPE (CQS) for Hive insert

    Adding fast_extract() and hive_insert() CQS operator syntax to be able to force shapes
of Hive insert statements.
    
    Example:
    
    control query shape hive_insert(cut);
    explain insert into hive.hive.t values(1,1);
    
    Note: I don't think this fix works for UNLOAD, since that seems to be
    an "ExeUtil" statement that gets executed in two phases.
