Description
In current WASB (Windows Azure Storage - Blob) implementation, when rename operation succeeds, WASB will update the parent folder's "last modified time" property. By default we do not acquire lease on this folder when updating its property and simply pass "null" to it.
In HBase scenario, when doing distributed log splitting, there might be a case that multiple processes from different region servers will access the same folder, and randomly we will see this exception in regionserver's log, which makes log splitting fail.
So we should acquire the lease when updating the folder property rather than pass "null" to it.
