Hadoop-2.2.0 "It looks like you are making an HTTP request to a Hadoop IPC port. "

Question

I am new to hadoop.After I have installed the hadoop-2.2.0 on single-node,I visited the url:localhost:9000,it returned the following result:

It looks like you are making an HTTP request to a Hadoop IPC port. This is not the correct port for the web interface on this daemon.

I have configured my core-site.xml as below:

<property>
    <name>fs.default.name</name>
    <value>hdfs://localhost:9000</value>
    <description>The name of the defaultfile system. Either the literal string "local" or a host:port.
    </description>
    <final>true</final>
</property>

How can I solved the problem? Thanks in advance.

Answer 1

Hope this helps: http://hostname:50070/dfshealth.html http://hostname:50075/datanode.html http://hostname:8088/cluster http://hostname:8042/node

Or simply: http://hostname:50070/ http://hostname:50075/ http://hostname:8088/ http://hostname:8042/

Answer 2

check this out, http://localhost:50070 It works fine on win10. it's already discussed here.

Answer 3

For a basic single node configuration here the web interfaces (hadoop1 is my hostname):

• Resource Manager: http://hadoop1:8088
• Web UI of the NameNode daemon: http://hadoop1:50070
• HDFS NameNode web interface: http://hadoop1:8042

Answer 4

You can't "browse" to a hdfs address: that is used internally by hadoop.

Answer 5

There are other HTTP ports that would run in server for monitoring. Example: 50070, 8088, 9870, 9864, 9868, 16010, 16030

Hadoop IPC(Inter Process Communicator) ports (Eg. 9000) cannot be accessed through your web browser.

You can find the ports that can be accessed in browser by the following command:

lsof -i -P -n | grep LISTEN

For example, the ports in my server were:

Hadoop Cluster - http://server-name:8088/cluster

Hadoop NameNode/DFS Health - http://server-name:9870/dfshealth.html#tab-overview

Hadoop DataNode - http://server-name:9864/datanode.html

Hadoop Status - http://server-name:9868/status.html

HBase Master Status - http://server-name:16010/master-status

HBase Region server - http://server-name:16030/rs-status
