Subject: Fwd: Hadoop 2.7.3 cluster namenode not starting

Hello

I have a 3-node cluster where I have installed hadoop 2.7.3. I have updated core-site.xml,
mapred-site.xml, slaves, hdfs-site.xml, yarn-site.xml, hadoop-env.sh files with basic settings
on all 3 nodes.

When I execute start-dfs.sh on the master node, the namenode does not start. The logs contain
the following error -
2017-04-27 14:17:57,166 ERROR org.apache.hadoop.hdfs.server.namenode.NameNode: Failed to start
namenode.

I have changed the port number multiple times, every time I get the same error. How do I get
past this?
