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.
Healthy Impala Daemon: 0. Concerning Impala Daemon: 1. Total Impala Daemon: 3. Percent healthy: 0.00%. Percent healthy or concerning: 33.33%. Critical threshold: 90.00%.
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:
# impala-shell Starting Impala Shell without Kerberos authentication Error connecting: TTransportException, Could not connect to vm16.test.com:21000 Welcome to the Impala shell.
