[TRAFODION-3148] Fix UPDATE STATS bug on Hive tables w/ column _DIVISION_1_
This fixes a bug concerning sample tables created by UPDATE STATISTICS on
Hive tables.
When a Hive table had a column named "_DIVISION_1_" (or any other reserved
Trafodion column name), the UPDATE STATISTICS command would fail if a sample
table needed to be created. The failure would occur because we would not
include "_DIVISION_1_" etc. in the select list of the UPSERT/SELECT statement
used to populate the sample table.
This has been fixed.
