HadoopJob(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A Dataproc job for running Apache Hadoop MapReduce <https://hadoop.apache.org/docs/current/hadoop-mapreduce-client/hadoop-mapreduce-client-core/MapReduceTutorial.html> jobs on Apache Hadoop YARN <https://hadoop.apache.org/docs/r2.7.1/hadoop-yarn/hadoop-yarn-site/YARN.html>.

Attributes
Name	Description
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.
jar_file_uris	Sequence[str] 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.

Classes

PropertiesEntry

PropertiesEntry(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The abstract base class for a message.

Parameters
Name	Description
kwargs	dict Keys and values corresponding to the fields of the message.
mapping	Union[dict, .Message] A dictionary or message to be used to determine the values for this message.
ignore_unknown_fields	Optional(bool) If True, do not raise errors for unknown fields. Only applied if mapping is a mapping type or there are keyword parameters.
