Todd Lipcon commented on HBASE-4169:
------------------------------------

The non-HDFS one doesn't make much sense to me... I tried the chmod trick on 
our NFS filer here and it doesn't work -- opened a file from one node for 
write, and was able to continue to write/fsync even after I chmodded on a 
different node. It might be that there are some specific file systems where 
this works, but it's far from the norm in my experience.

> FSUtils.recoverFileLease uses HDFS's recoverLease method to get lease before 
> splitting hlog file.
> This might not work for other filesystem implementations.
