> metastore JDO filter pushdown for integers may produce unexpected results
> with non-normalized integer columns
> -------------------------------------------------------------------------------------------------------------
>
> Key: HIVE-6052
> URL: https://issues.apache.org/jira/browse/HIVE-6052
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.12.0, 0.13.0

>
> If integer partition columns have values stores in non-canonical form, for
> example with leading zeroes, the integer filter doesn't work. That is because
> JDO pushdown uses substrings to compare for equality, and SQL pushdown is
> intentionally crippled to do the same to produce same results.
> Probably, since both SQL pushdown and integers pushdown are just perf
> optimizations, we can remove it for JDO (or make configurable and disable by
> default), and uncripple SQL.
