The error message "Error occurred while opening a session" in Impala typically indicates that there was an issue with connecting to the Impala daemon or the Impala service.
To troubleshoot this error, you can try the following steps:
1. Check if the Impala daemon is running. You can use the command "sudo service impala-daemon status" to verify if the daemon is running or not. If it is not running, start the daemon using "sudo service impala-daemon start".
2. Check if the Impala service is running. You can use the command "sudo service impala-state-store status" to verify if the service is running or not. If it is not running, start the service using "sudo service impala-state-store start".
3. Check if the Impala configuration is correct. Verify the configuration files for Impala and make sure that they are set up correctly.
4. Check if there are any network issues. Verify that the network connection between the client and the Impala service is working properly.
5. Check if there are any firewall issues. Verify that the firewall settings are not blocking the Impala connection.
If none of the above steps resolve the issue, you may need to consult the Impala documentation or seek assistance from the Impala support team.
