> Thanks @lirui-apache , can you explain what bug in Hive? When we specify a filter like `timestamp '2018-08-08 08:08:09' = p2`, the type of the timestamp literal is `TIMESTAMP(0)`. And when we try to get an object inspector for such type, HiveCatalog will throw exception because the timestamp precision is not supported. Perhaps the root cause is that `FlinkTypeFactory::leastRestrictive` returns the 1st type when we call it with a `List(TIMESTAMP(0), TIMESTAMP(9))`. Therefore, if we change the filter to `p2 = timestamp '2018-08-08 08:08:09'` the query will pass. But anyway, I think it's OK to skip generating filter for timestamp partitions because HMS doesn't support such filters. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
