[TRAFODION-2352] UPDATE STATS may fail with error 8446 on Hive tables
There are two fixes here.
1. Fix for JIRA TRAFODION-2352: Propagate the CQD
HIVE_MAX_STRING_LENGTH_IN_BYTES to the grandchild tdm_arkcmp process if needed
to avoid possible error 8446 on Hive tables with very long varchar columns.
2. Fix an unrelated minor problem: Warning 9234 may occur
non-deterministically in test scripts for incremental UPDATE STATS. A previous
pull request, https://github.com/apache/incubator-trafodion/pull/719, had
changed most such warnings so they are emitted only when UPDATE STATS logging
is 'ON'. I missed a couple; this change takes care of them.
