Cannot see Hadoop UI which is running inside docker container, in browser #3625
Description
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 [email protected]
ssh-copy-id [email protected]
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:
[email protected]
[email protected]
core-site.xml had this contents in three containers:
/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.
