      Description

      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.
