I have a Hadoop cluster of three containers on three different hosts; the details are in following:
 First, I install "weave net" in my three hosts (150.20.11.133,150.20.11.136,150.20.11.157) via this command:

```
 sudo curl -L git.io/weave -o /usr/local/bin/weave
 sudo chmod a+x /usr/local/bin/weave
 eval $(weave env)

```

Then I connected three host together via weave. In fact, I ran this command in three hosts:

For example in 150.20.11.133:

```
 Weave launch 150.20.11.136 150.20.11.157

```

After connecting three hosts together, I had to make **SSH** passwordless between Master and Workers. Therefore, I did there works:
In each host:

```
 ssh-keygen -t rsa

```

In master:

```
 ssh-copy-id spark@172.28.10.136
 ssh-copy-id spark@172.28.10.157
 cat /home/user/.ssh/id_rsa.pub >> /home/user/.ssh/authorized_keys

```

As a result of that, I could run **SSH** without password from master host to slaves.

In each host, I built my Docker file which had configuration for hadoop then I ran that:

In Master:

```
 docker run -v /home/user/.ssh:/root/.ssh --privileged -p 52222:22 
 -e WEAVE_CIDR=10.32.0.1/12 -ti my-hadoop

```

In slave1:

```
 docker run -v /home/user/.ssh:/root/.ssh --privileged -p 52222:22 
 -e WEAVE_CIDR=10.32.0.2/12 -ti my-hadoop

```

In slave2:

```
 docker run -v /home/user/.ssh:/root/.ssh --privileged -p 52222:22 
 -e WEAVE_CIDR=10.32.0.3/12 -ti my-hadoop

```

In each container, I ran these commands:

```
 chmod 700 ~/.ssh/
 chmod 600 ~/.ssh/*
 chown -R root ~/.ssh/
 chgrp -R root ~/.ssh/
 chmod -R 750 /root/.ssh/authorized_keys

```

In master container, I ran this command to run **SSH localhost**:

```
 ssh-keygen -f "/root/.ssh/known_hosts" -R localhost

```

Also, I started **SSH** service in each container node:

```
 service ssh restart

```

So, I could run **SSH** from master container to slaves without password.
For hadoop configuration, I did these works:
First in master node:

```
  hadoop namenode -format

```

**workers** had these contents in three contaiers:

```
  root@10.32.0.2
  root@10.32.0.3

```

**core-site.xml** had this contents in three containers:

```
  <configuration>
    <property>
       <name>fs.defaultFS</name>
       <value>hdfs://root@10.32.0.1:9000</value>
    </property>
  </configuration>

```

**hdfs-site.xml** had these contents in three containers too:

```
   <configuration>
    <property>
       <name>dfs.replication</name>
       <value>1</value>
    </property>
    <property>
       <name>dfs.namenode.name.dir</name>
       <value>file:/usr/local/hadoop_store/hdfs/namenode</value>
    </property>
    <property>
       <name>dfs.datanode.data.dir</name>
       <value>file:/usr/local/hadoop_store/hdfs/datanode</value>
    </property>
   </configuration>

```

Then I ran this in master container:

```
   /opt/hadoop/sbin/start-dfs.sh

```

When I ran **jps** in each container, I received these results:
In Master container:

```
   483 SecondaryNameNode
   231 NameNode
   747 Jps

```

In each Worker:

```
   117 DataNode
   186 Jps

```

The problem is, I want to see Hadoop UI in browser. I run this URL, but it does not show anything:

```
    http://10.32.0.1:8088

```

By the way, I have already exposed these ports in docker file:

```
    EXPOSE 22 9000 8088 50070 50075 50030 50060

```

Would you please tell me how I can see Hadoop cluster UI in browser?

Any help would be appreciated.
