Attributes

NameDescription
main_jar_file_uri str
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'
main_class str
The name of the driver's main class. The jar file containing the class must be in the default CLASSPATH or specified in ``jar_file_uris``.
args Sequence[str]
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 may occur that causes an incorrect job submission.

Optional. Jar file URIs to add to the CLASSPATHs of the Hadoop driver and tasks.
file_uris Sequence[str]
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.
archive_uris Sequence[str]
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 Sequence[google.cloud.dataproc_v1.types.HadoopJob.PropertiesEntry]
Optional. A mapping of property names to values, used to configure Hadoop. Properties that conflict with values set by the Dataproc API may be overwritten. Can include properties set in /etc/hadoop/conf/*-site and classes in user code.
logging_config google.cloud.dataproc_v1.types.LoggingConfig
Optional. The runtime log config for job execution.
