Jing Zhao commented on HDFS-4248:
---------------------------------
I tried to run Daryn's new testcase without his fix, and could get a similar
result with Nicholas, i.e., for new rename to existing dir with OVERWRITE opt,
the old lease is removed instead of renamed. (This is because in
FSDirectory#unprotectedRenameTo(String, String, long, Options.Rename...),
FSNamesystem#removePathAndBlocks is called in the end which removes leases with
prefix path src. Daryn's patch can fix the bug since the unprotectedChangeLease
call is now moved before calling FSNamesystem#removePathAndBlocks.)
