public access to hadoop web interfaces

All of the Web UIs for hadoop services (yarn history server, resourcemanger; HDFS namenode webUI; etc) all seem to bind to internal addresses on the cluster and then cant be seen outside of the cluster.   

 

# ss -n | grep 19888

tcp    ESTAB      0      0      172.23.0.1:19888              172.23.0.1:34148              

tcp    ESTAB      0      0      172.23.0.1:34148              172.23.0.1:19888              

 

Id like these to be accessable via a different interface (10.X.Y.Z) which whould allow users to see the pages.

 

Is this possible?

Re: public access to hadoop web interfaces

@DaveO,

 

If you want all ports for HDFS and YARN to bind to the wildcard address, you can configure this in Cloudera Manager.

 

In Configuration, search for:

 

"Wildcard Address"

 

You can enable this and restart the roles as desired.

 

Note, it will change *all* ports for that role, not just the web UIs.
