Ensure the hadoop executable is in the PATH. Note that this jar file should contain all the third party dependencies that your job has this can be achieved with the Maven assembly plugin or sbt-assembly. By default, SIMR sets the value to the number of nodes in the cluster. This value must be at least 2, otherwise no executors will be present and the task will never complete.

Assuming spark-examples. SIMR expects its different components to communicate over the network, which requires opening ports for communication. Instead the ports are in the ephemeral range For SIMR to function properly ports in the ephemeral range should be opened in firewalls. If these variables are not set, the runtime script will default to a simr. By default SIMR figures out the number of task trackers in the cluster and launches a job that is the same size as the cluster.

The following sections are targeted at users who aim to run SIMR on versions of Hadoop for which jars have not been provided.

I am working with Databricks notebook and I synced it with GitHub. We are 2 members working on 2 different branches in Github repo. When we ran Azure Data Factory activity on that notebook, It ran the latest version of that notebook.

So whats the purpose of having GitHub as version control since we can't have control over Notebook version while executing from outside. What If many developers commit their changes but at the EOD we need master branch changes to be executed which are most stable one. Databricks notebook does not reload from the git.
