     [ https://issues.apache.org/jira/browse/HIVE-3422?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jean Xu updated HIVE-3422:
--------------------------

    Release Note: 
For alter table with partial partition spec, DDLSemanticAnalyzer will call table.getPartitions
to get all the partitions and insert them to outputs. DDLTask::alterTable will get all the
partitions for
ALTERPROTECTMODE, and alter the mode for all the partitions.
          Status: Patch Available  (was: Open)

> 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
