> We've been testing HBase on clusters running trunk and seen an issue where
> they seem to lose their HDFS leases after a couple of hours of runtime. We
> don't quite have enough data to understand what's happening, but the NN is
> expiring them, claiming the hard lease period has elapsed. The clients report
> no error until their output stream gets killed underneath them.
