Aaron T. Myers commented on HDFS-3849:
--------------------------------------
The latest patch looks almost perfect to me, and good test cases, Colin.
One small nit: there's no need for enabling the DT config in the new test case
in TestCheckpoint. +1 once this is addressed.
> When re-loading the FSImage, we should clear the existing genStamp and leases.
