> As for what happens to the leases after renaming [...] I think namenode
> should release them
I agree, I posed this question in the last paragraph of the first comment on
this jira. If Nicholas and others think that's the right to do, I can address
on another jira since I think this issue is a bit more severe.

It sounds reasonable to me. I only has a concern that rename may cause a lot
of lease recoveries happening at the same time. BTW, I think there is a bug in
current code. Let's discuss it in more details in the new JIRA HDFS-4258.
