> 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.
