In CDH5 Cloudera Manager, Hive is working fine. After restarting the Impala service, few minutes later Impala service moves to bad health , and we are getting following error after starting the Impala service.
Impala catalog server and state-store are configured in same host where Hive is configured, and 3 Impala deamon are configured in seperate host.
Following is the messgae while staring impala shell:
Starting Impala Shell without Kerberos authentication
Error connecting: TTransportException, Could not connect to vm16.test.com:21000
Welcome to the Impala shell. Press TAB twice to see a list of available commands.
