Hairong Kuang commented on HADOOP-5481:
---------------------------------------
Kan, could you please explain why you need this change? Heartbeat handling is
very critical to dfs so normally we are very cautions about making any change
to it. Also lease recovery is added to the system to support append/sync
feature which may undergo some future change,
> Namenode should return lease recovery request with other requests

> HADOOP-5034 modified NN to return both replication and deletion requests to
> DN in one reply to a heartbeat. However, the lease recovery request is still
> sent separately by itself. Is there a reason for this? If not, I suggest we
> combine them together. This will make it less confusing when adding new types
> of requests, which are combinable as well.
