[TRAFODION-2465] Fix two bugs
This set of changes fixes two problems (both introduced by me):
1. When UPDATE STATISTICS retries a statement, and the statement continues
to fail, the error diagnostics are incorrect. The root cause of the error is
not reported, and some irrelevant errors are reported (i.e. 8609, error on
transaction rollback, which happens because the Executor sometimes has already
rolled back the transaction when UPDATE STATISTICS attempts a ROLLBACK after a
statement failure). This bug was introduced when I rewrote the retry logic in
JIRA TRAFODION-2341. My unit test was not thorough enough. (ustat/hs_cli.cpp)
2. Performing UPDATE STATISTICS ON EXISTING COLUMNS PERSISTENT would fail
on Hive tables with varchar columns over 200000 characters long. I fixed a
similar issue in JIRA TRAFODION-2322, but failed to notice that this issue
existed separately in the ON EXISTING COLUMNS code path. (ustat/hs_parser.cpp).
