> When a node (DN+RS) has machine/OS level failure, another RS will try to do
> lease recovery for the log file. It will retry for every
> hbase.lease.recovery.dfs.timeout (default to 61s) from the second time. When
> the hdfs configuration is not properly configured (e.g. socket connection
> timeout) and without patch HDFS-4721, the lease recovery time can exceeded
> the timeout specified by hbase.lease.recovery.dfs.timeout. This will lead to
> endless retries and preemptions until the final timeout.
