Subject [jira] [Commented] (HBASE-8341) RestoreSnapshotHandler.prepare() is not called by SnapshotManager
Date Mon, 15 Apr 2013 04:50:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8341?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13631499#comment-13631499

Enis Soztutar commented on HBASE-8341:
--------------------------------------

Thanks for looking in. That part re-arranges acquiring of the table lock with loading the
table descriptor. We used to load the table desc, then acquire the lock, but we should swap
their order to guard against the race between alter/rename table and snapshot operation.

> In HBASE-7848, we added table lock to enabled/disabled snapshot handlers, and fixed SnapshotManager
to call CloneSnapshotHandler.prepare() in HBASE-7957. It seems that we overlooked the RestoreSnapshotHandler.prepare().
In this issue we should fix that so that we acquire the table lock in restore snapshot.
