Fields
`args[]`	`string` Optional. The arguments to pass to the driver. Do not include arguments, such as `-libjars` or `-Dfoo=bar`, that can be set as job properties, since a collision might occur that causes an incorrect job submission.
`jarFileUris[]`	`string` Optional. Jar file URIs to add to the CLASSPATHs of the Hadoop driver and tasks.
`fileUris[]`	`string` Optional. HCFS (Hadoop Compatible Filesystem) URIs of files to be copied to the working directory of Hadoop drivers and distributed tasks. Useful for naively parallel tasks.
`archiveUris[]`	`string` Optional. HCFS URIs of archives to be extracted in the working directory of Hadoop drivers and tasks. Supported file types: .jar, .tar, .tar.gz, .tgz, or .zip.
`properties`	`map (key: string, value: string)` Optional. A mapping of property names to values, used to configure Hadoop. Properties that conflict with values set by the Dataproc API might be overwritten. Can include properties set in `/etc/hadoop/conf/*-site` and classes in user code. An object containing a list of `"key": value` pairs. Example: `{ "name": "wrench", "mass": "1.3kg", "count": "3" }`.
`loggingConfig`	`object (LoggingConfig)` Optional. The runtime log config for job execution.
Union field `driver`. Required. Indicates the location of the driver's main class. Specify either the jar file that contains the main class or the main class name. To specify both, add the jar file to `jar_file_uris`, and then specify the main class name in this property. `driver` can be only one of the following:
`mainJarFileUri`	`string` The HCFS URI of the jar file containing the main class. Examples: 'gs://foo-bucket/analytics-binaries/extract-useful-metrics-mr.jar' 'hdfs:/tmp/test-samples/custom-wordcount.jar' 'file:///home/usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar'
`mainClass`	`string` The name of the driver's main class. The jar file containing the class must be in the default CLASSPATH or specified in `jarFileUris`.
