DESCRIPTION

Creates Jar Job in Databricks. Script uses Databricks API 2.0 create job query: https://docs.azuredatabricks.net/api/latest/jobs.html#create If the job name exists it will be updated instead of creating a new job.

EXAMPLES

EXAMPLE 1

Add-DatabricksJarJob -BearerToken $BearerToken -Region $Region -JobName "Job1" -SparkVersion "5.3.x-scala2.11" -NodeType "Standard_D3_v2" -MinNumberOfWorkers 2 -MaxNumberOfWorkers 2 -Timeout 100 -MaxRetries 3 -ScheduleCronExpression "0 15 22 ? * *" -Timezone "UTC" -JarPath "folder/Test.jar" -JarMainClass 'com.test.me' -JarParameters "val1", "val2" -Libraries '{"jar": "DBFS:/mylibraries/test.jar"}'

The above example create a job on a new cluster.
