Subject [jira] [Commented] (HIVE-2777) ability to add and drop partitions atomically
Date Wed, 08 Feb 2012 20:03:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-2777?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13203913#comment-13203913

Aniket Mokashi commented on HIVE-2777:
--------------------------------------

I am adding deleteData option there, deletion of data itself cannot be made atomic. But, its
good to have as part of the api. deleteData=true attempts to delete the data.

> Hive should have ability to atomically add and drop partitions. This way admins can change
partitions atomically without breaking the running jobs. It allows admin to merge several
partitions into one.
> Essentially, we would like to have an api- add_drop_partitions(String db, String tbl_name,
List<Partition> addParts, List<List<String>> dropParts, boolean deleteData);
> This jira covers changes required for metastore and thrift.
