namenode in loop forever leasemanager HDFS-4882

Hi,

Recently, we are facing “namenode’s leasemanager from looping forever”. It will bring namenode to a state nothing could be executed
other than rolling it.

It looks like is a known issue fixed in later versions  as per the ticket https://issues.apache.org/jira/browse/HDFS-4882.

We are currently running cdh4.7.1.p0.47, the fix is available in CDH 5.4/apache 2.6.1. In this jira, there is a patch for this issue that has
been tested in later version. I wanted to check if anybody who faced this problem tried to use this patch and compile cdh4.7.1 code and
was the issue fixed?

Thanks

RK
