> Project: Hive
> Issue Type: Improvement
> Components: Metastore
> Reporter: Jean Xu
> Assignee: Jean Xu
> Priority: Minor
>
> Currently if you have a table t with partition columns c1 and c2 the
> following command works:
> ALTER TABLE t PARTITION (c1 = 'x', c2 = 'y') ENABLE NO_DROP;
> The following does not:
> ALTER TABLE t PARTITION (c1 = 'x') ENABLE NO_DROP;
> We would like all existing partitions for which c1 = 'x' to have NO_DROP
> enabled when a user runs the above command
