Since a renewer may expire, the stored renewer can be different. Added a comment in the code. > Why did we choose to use volatile for sleepPeriod and synchronized for > gracePeriod and other periods? Used synchronized for both now. > Share LeaseChecker thread among DFSClients > ------------------------------------------ > > Key: HDFS-1865 > URL: https://issues.apache.org/jira/browse/HDFS-1865 > Project: Hadoop HDFS > Issue Type: Improvement > Components: hdfs client > Reporter: Tsz Wo (Nicholas), SZE > Assignee: Tsz Wo (Nicholas), SZE > Attachments: h1865_20110503.patch, h1865_20110504.patch, > h1865_20110508.patch > > > Each {{DFSClient}} runs a {{LeaseChecker}} thread within a JVM.
