Sergey Shelukhin updated HIVE-6945:
-----------------------------------
Description:
1) Direct SQL is broken on Oracle due to the usage of NUMBER type which is
translated by DN into decimal rather than long. This appears to be specific to
some cases because it seemed to have worked before (different version of
Oracle? JDBC? DN? Maybe depends on whether db was auto-created).
2) When partition dropping code falls back to JDO, it creates objects to
return, then drops partitions. It appears that dropping makes DN objects
invalid. We create metastore partition objects out of DN objects before drop,
however the list of partition column values is re-used, rather than copied,
into these. DN appears to clear this list during drop, so the returned object
becomes invalid and the exception is thrown.
