Accessing Impala Web User Interfaces

Impala 1.2.x and newer provides Web user interfaces for the statestore, impalad, and catalog daemons. These Web UIs are accessible through the following URLs and ports, respectively:

Copy
http://master-node-public-dns-name:25000 http://master-node-public-dns-name:25010 http://master-node-public-dns-name:25020

You can set up an SSH tunnel to the master node in Amazon EC2 to view the Web UIs on your local machine using the following example commands:

Copy
$ ssh -i PERM_FILE -nTxNf -L 127.0.0.1:25000:master-node-public-dns-name:25000 \ hadoop@master-node-public-dns-name $ ssh -i PERM_FILE -nTxNf -L 127.0.0.1:25010:master-node-public-dns-name:25010 \ hadoop@master-node-public-dns-name $ ssh -i PERM_FILE -nTxNf -L 127.0.0.1:25020:master-node-public-dns-name:25020 \ hadoop@master-node-public-dns-name
