Node Manager cannot able to start in Hadoop 2.6.0 (Connection refused)

I have installed hadoop 2.6.0 multi-node cluster in EC2 instance(ubuntu 14.04 64 bit). All demons(NameNode,SecondaryNameNode,ResourceManager) in master is up,but in slave machine only DataNode is up NodeManager is shutting down due to connection refuse.

Kindly help me in this regard. Thanks in advance

The log file of my NodeManager is below:

Telnet command:

How is it taking 8031 port for resource manager ? I haven't giving in my hadoop configuration files(coresite.xml,mapred-site.xml,hdfs-site.xml) which is above.

Solution

  • I have made modifications in mapred-site.xml and yarn-site.xml which solved my issue.Since I haven't mentioned the host name property value for resource manager in yarn-site.xml it was trying to connect with the address 0.0.0.0 which was the cause for connection refused exception.

    mapred-site.xml

    <property>
    <name>mapreduce.framework.name</name>
    <value>yarn</value>
</property>

    yarn-site.xml

    <property>
    <name>yarn.resourcemanager.hostname</name>
    <value>ec2-52-26-161-203.us-west-2.compute.amazonaws.com</value>
</property>
