> issues with dropping partitions on Oracle

>
> 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.
