Troubleshooting steps for common errors in Cloudera Streaming Community Edition.

'Port is already in use' error message

You need to verify that the required ports are available and not already in use.

Use one of the following commands to see which ports are in used:

• MacOS/Windows: netstat -an
• Linux: netstat -nlp or ss -nlp

exited 137 error message

If you see tmp-sqlio-1 exited with code 137 error message in the Streaming SQL Engine log, you need to modify the docker memory settings.

Open Docker Desktop, go to the Settings > Resources, and set memory limit to 4 GB

If you need to restart Cloudera Streaming Community Edition from scratch, you can run the following command to remove specific volumes and containers locally from Docker:

docker-compose down
docker rm <container_name_1> <container_name2>
docker volume rm <volume_name_1> <volume_name2>
docker-compose up -d
