Subject [jira] [Commented] (HIVE-3646) Add 'IGNORE PROTECTION' predicate for dropping partitions
Date Wed, 28 Nov 2012 17:58:58 GMT


Andrew Chalfant commented on HIVE-3646:

I spoke with Kevin Wilfong and he said for me to just go ahead and make the changes to the
docs, but I need a confluence account and he doesn't have permissions to make the account
for me. Can you please make a confluence account with edit permissions for me please?

> There are cases where it is desirable to move partitions between clusters. Having to
undo protection and then re-protect tables in order to delete partitions from a source are
multi-step and can leave us in a failed open state where partition and table metadata is dirty.
By implementing an 'rm -rf'-like functionality, we can perform these operations atomically.
