Error connecting: <class 'thrift.transport.TTransport.TTransportException'>

Question

I have installed Cloudera Impala v0.4 via Cloudera Manager 4.1.3

my cluster comprises of only to slave machines

slave1 --> Impala Daemon, State Store daemon
slave2 --> Impala Daemon

So, I am able to run impala shell on these machines-

>impala-shell

The problem is, when i run the command (in slave1/slave2)

[Not connected] > connect impalad-host:21000

I get the following error:

Error connecting: class 'thrift.transport.TTransport.TTransportException'
Could not connect to impalad-shell:21000

Here impalad-host is the host name by default running on port no 21000.

How do I configure the host name and the port no?

Although this is a three year old question, I am still going to add my two cents for anyone who lands up on this page looking for a solution-

Look here for an answer Modifying Impala Startup Options

Configuring Impala Startup Options through the Command Line

When you run Impala in a non-Cloudera Manager environment, the Impala server, statestore, and catalog services start up using values provided in a defaults file, /etc/default/impala.

This file includes information about many resources used by Impala. Most of the defaults included in this file should be effective in most cases. For example, typically you would not change the definition of the CLASSPATH variable, but you would always set the address used by the statestore server. Some of the content you might modify include:

IMPALA_STATE_STORE_HOST=127.0.0.1

IMPALA_STATE_STORE_PORT=24000

IMPALA_BACKEND_PORT=22000

IMPALA_LOG_DIR=/var/log/impala
