    Description

      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.
