Subject datanode is unable to connect to namenode
Date Tue, 28 Jun 2016 19:09:24 GMT
Hi all,

I have setup two nodes cluster with security enabled. I have everything
running successful like namenode, datanode, resourcemanager, nodemanager,
jobhistoryserver etc. But datanode is unable to connect to namenode, as i
can see only one node on the web UI. checking logs of datanode gives
following warning:

*WARN org.apache.hadoop.hdfs.server.datanode.DataNode: Problem connecting
to server: hadoop-master/192.168.23.206:8020 <http://192.168.23.206:8020>*

Rest of the things look fine. Please help me in this regard, what could be
the issue?
