Navis commented on HIVE-5240:
-----------------------------
Should partition columns be ignored, instead of throwing exception?
> Column statistics on a partitioned column should fail early with proper error
> message

> When computing column statistics on a partitioned table, if one of the
> columns equals the partitioned column then IndexOutOfBoundsException is
> thrown.
> Following analyze query throws IndexOutOfBoundsException during semantic
> analysis phase
> {code}hive> analyze table qlog_1m_part partition(year=5) compute statistics
> for columns year,month,week,type;
> FAILED: IndexOutOfBoundsException Index: 1, Size: 0{code}
> If the partitioned column is specified at last like below then the same
> exception is thrown at runtime
> {code}hive> analyze table qlog_1m_part partition(year=5) compute statistics
