Analytic Logs

You can specify the path for analytic logs in the configuration file. The file path can be changed to any path but must always be within the base path.

For example, you can determine the analytic files in the /data/other/logs .

Spark UI

If the Spark UI is not available on port 8080 of the Spark master server, then do the following:

  • Check the Spark start-up logs and check if the status of Spark UI port if 8080 is not the default port or if there is another service using the port.

  • If the UI is not accessible, run some curl commands to check the core and memory in the cluster.

    $ curl -s https://<ip-addres>:8080 | grep -A 2 'Memory in use'
     curl -s https://<ip-address>:8080 | grep -A 2 'Cores in use'
