> 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.
