--------------------------------------------------------
There is no assignee for HDFS-2296.
The change in this JIRA is similar to how Accumulo handles lease recovery.
Since hdfs API change would take some time, I prefer putting in better
safeguard through this JIRA.

> Apache Accumulo has moved its write-ahead log to HDFS. I modeled the lease
> recovery for Accumulo after HBase's lease recovery. During testing, we
> experienced data loss. I found it is necessary to wait until recoverLease
> returns true to know that the file has been truly closed. In FSHDFSUtils,
> the return result of recoverLease is not checked. In the unit tests created
> to check lease recovery in HBASE-2645, the return result of recoverLease is
> always checked.
> I think FSHDFSUtils should be modified to check the return result, and wait
> until it returns true.
