Tsz Wo (Nicholas), SZE commented on HDFS-2229:
----------------------------------------------
Hi Todd, the detected deadlocks seem false alerts since setBlockTotal() is only
invoked in activate(..) before starting the lease monitor thread.
BTW, are you running it against trunk? The line numbers are off.
