Should we try/catch null exception incase any of these becomes null?

> *[Description]*
> Failure in direct SQL processing do not undo the changes made to database
> before falling back to JDO based processing. Thus results in stale/dangling
> entries in database forever.
> For instance, during dropPartitions() direct SQL processing, after dropping
> rows from few tables(like PARTITIONS, PARTITION_PARAMS, PARTITION_KEY_VALS
> etc), it causes typecast exception in dropStorageDescriptors() and fallback
> to JDO processing. But datanucleus JDO processing cannot delete rows from
> remaining tables(i.e., from sds, serdes, sds_params, serde_params, sort_cols,
> bucketing_cols, skewed cols/values/location if any for the partitions) since
> the partition is already deleted in the same transaction during direct SQL
> processing.
