>         Environment: all
>            Reporter: jinzheng

>     After the change of  HIVE-4914, we always push the partition expression to metastore, to avoid filtering partition by partition names.
>     And HIVE-4914 added some protection in Partition pruner, in case that metastore may not have api of get_partitions_by_expr.
>     Therefore, we should also add similar protection to another calling point, when dealing with "alter table drop partition".
