Subject [jira] [Commented] (HDFS-6757) Simplify lease manager with INodeID
Date Thu, 31 Jul 2014 19:11:41 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14081288#comment-14081288

Colin Patrick McCabe commented on HDFS-6757:
--------------------------------------------

Ah.  I see what you're saying.  We don't remove the inode at all if it's in an older snapshot,
so we don't get a chance to remove the lease manager entry just by looking at removedINodes.
 Thanks for the explanation.

> Currently the lease manager records leases based on path instead of inode ids. Therefore,
the lease manager needs to carefully keep track of the path of active leases during renames
and deletes. This can be a non-trivial task.
> This jira proposes to simplify the logic by tracking leases using inodeids instead of
paths.
