Hi ,
I have a server with multiple dns bound to it. I have setup single node
hadoop cluster (3.1.2 release) on my server and i want to use particular
hostname for my hadoop server.
I am able to start namenode and secondary namenode on specific DNS address
but i am not able to do the same for datanode. Here is what i tried in
hdfs-site.xml file as per documentation
<property>
<name>dfs.datanode.http.address</name>
<value>myhostname:9864</value>
</property>
<property>
<name>dfs.datanode.address</name>
<value>myhostname:9866</value>
</property>
<property>
<name>dfs.datanode.ipc.address</name>
<value>myhostname:9867</value>
</property>
But above configuration doesn't work. The namenode UI still show the a
different hostname for datanode http address. I can see specific propertiy
for namenode and secondary namenode(dfs.namenode.http-address) which sets
the host to bind. But there is none for datanode.
Any idea how to change bind host for datanode?
