Impala not working in cloudera-quickstart-vm-5.10 as Impala Daemon is not starting.
Following is the status of the three required roles for Impala:
- Impala Daemon is down
- Impala Catalog Server has bad health &
- Impala StateStore has good health
Getting following error messages:

Could not read the root directory at hdfs://quickstart.cloudera:8020. Error was: Call From quickstart.cloudera/127.0.0.1 to quickstart.cloudera:8020 failed on connection exception: java.net.ConnectException: Connection refused; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused

Aborting Impala Server startup due to improper configuration. Impalad exiting.
Tried restarting the service through command line.
[cloudera@quickstart ~]$ sudo service impala-server restart
Stopped Impala Server: [ OK ]
Started Impala Server (impalad): [ OK ]
[cloudera@quickstart ~]$ service impala-server status
Impala Server is dead and pid file exists [FAILED]
Still it is not working. Not sure if I can do some configuration changes for it or not. If so, could not find what exactly can be changed for it to work.
