Hi I am following this below guide in link for VirtualBox Solaris Zones Hadoop installation.

Oracle Solaris Zones Hadoop Setup

I was able to successfully follow till step 10. Once I tried to check report I am getting this error::

adoop@name-node:~$ hadoop dfsadmin -report

14/05/17 16:45:12 INFO ipc.Client: Retrying connect to server: name-node/192.168.1.1:8020. Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS)

14/05/17 16:45:13 INFO ipc.Client: Retrying connect to server: name-node/192.168.1.1:8020. Already tried 1 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS)

....

14/05/17 16:45:21 INFO ipc.Client: Retrying connect to server: name-node/192.168.1.1:8020. Already tried 9 time(s);

retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS)

report: Call to name-node/192.168.1.1:8020 failed on connection exception: java.net.ConnectException: Connection refused

hadoop@name-node:~$

can someone kindly suggest resolution.

Also netstat shows this name-node.8021 . 0 0 128000 0 LISTEN
*.50030 . 0 0 128000 0 LISTEN

how to configure dfsadmin to port 8021 instead?

Probably this is too old question and you might have already solved it. But just in case if anyone is wondering.

in core-site.xml make the following changes

<property>
   <name>fs.defaultFS</name>
   <value>hdfs://192.168.1.1:8021/</value>
</property>

This will configure name node server port.
