Subject Fwd: Hadoop 2.7.3 cluster namenode not starting
Date Thu, 27 Apr 2017 09:18:07 GMT
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.
java.net.BindException: Problem binding to [master:51150]

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