Leases not properly getting renewed by clients
----------------------------------------------
Key: HDFS-2810
URL: https://issues.apache.org/jira/browse/HDFS-2810
Project: Hadoop HDFS
Issue Type: Bug
Components: hdfs client
Affects Versions: 0.23.0, 0.24.0
Reporter: Todd Lipcon
Priority: Critical
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.
