SSH might not be installed.

My example here assumes an Ubuntu/Linux image derived from since you did not specify the Dockfile contents at the time.

If your container can launch successfully (ignore the fact that your app is failing), you can just simply run ssh on the command-line to see (it will give you something similar to command not found)

To run commands inside Docker container: Since an Ubuntu image has bash installed, you can run like this:

docker exec -ti containername bash

Inside Docker container: (One of my containers where there is no SSH installed)

Spark History Server very slow when driver running on master node

Asked 2020-Jul-06 at 21:21

I launched Spark Thrift Server on the master node and it's the only job that is running on the cluster

The problem was having only 1 core instance as the logs were saved in HDFS so this instance became a bottleneck. I added another core instance and it's going much better now.

Another solution could be to save the logs to S3/S3A instead of HDFS, changing those parameters in spark-defaults.conf (make sure they are changed in the UI config too) but it might require adding some JAR files to work.

As it's unable to find driver class when you are running it from Jupyter Notebook, to avoid that you can try by copying mysql-connector-java-5.1.47.jar to the $SPARK_HOME/jars folder. It will resolve your driver issue as per my personal experience.
