@marmbrus While digging into Hive commit log, I found this
[HIVE-4888](https://issues.apache.org/jira/browse/HIVE-4888). Binary comparison
operators have been supported by `getPartitionsByFilter()` since Hive 0.13.
So my patch will break backward compatibility with Hive 0.12 and older. I
think the best we can do is to disable predicate pushdown in metastore if
`spark.sql.hive.metastore.version` is lower than 0.13. Since we're already
implementing this in `HiveShim`, code will be isolated and can be easily
removed when dropping support for old Hive versions in the future.
