unsafe interrupted condition check in DFSClient lease renewal thread
--------------------------------------------------------------------

Key: HDFS-1478
URL: https://issues.apache.org/jira/browse/HDFS-1478
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Joydeep Sen Sarma
Assignee: dhruba borthakur


the lease renewal thread bails out if thread interrupted condition is set:

while (clientRunning && !Thread.interrupted()) {

this seems incorrect. we have seen cases (MAPREDUCE-2157) where (apparently) log4j may be setting the interrupted condition. if that is the case - the lease renewal thread will terminate - and i think we have heard of cases where lease renewal is not happening. so these seem to fit.
