IMPALA-11795: Ignore high/low values stats for timestamp columns
Timestamp column stats are handled as LongColumnStatsData, similarly to
integer types, but high/low value handling is not yet implemented for
timestamps. If for some reason HMS returned high/low values for
timestamps columns a Precondition ("Unsupported type encountered in
setLowAndHighValue()") was hit in Catalogd leading to failing to load
the table.
Impala does not write high/low values for timestamp columns, so I don't
know what led to this state in HMS and could only reproduce the issue
by manipulating TAB_COL_STATS in the backing db of HMS.
Testing:
- only tested manually by manipulating TAB_COL_STATS in HMS's db
