The error message "Error occurred while opening a session" in Impala usually means that there was a problem connecting to the Impala daemon. This could be due to several reasons, such as:
1. Network connectivity issues: If there is a problem with the network configuration or connectivity, the Impala daemon may not be able to establish a connection with the client.
2. Configuration issues: If the Impala configuration files are not set up properly, the daemon may not be able to start or may not be able to communicate with the client.
3. Resource constraints: If the server running Impala is low on resources such as memory or CPU, the daemon may not be able to start or may not be able to handle incoming requests.
To resolve this issue, you can try the following:
1. Check the network connectivity between the client and server.
2. Verify that the Impala configuration files are set up properly.
3. Check the resource utilization on the server running Impala.
4. Restart the Impala daemon and try connecting again.
If the issue persists, you can check the Impala logs for more details on the error and seek help from the Impala community or support team.
