class Google::Apis::DataprocV1::HadoopJob

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

Attributes

archive_uris[RW]

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. Corresponds to the JSON property `archiveUris` @return [Array<String>]

args[RW]

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. Corresponds to the JSON property `args` @return [Array<String>]

file_uris[RW]

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. Corresponds to the JSON property `fileUris` @return [Array<String>]

jar_file_uris[RW]

Optional. Jar file URIs to add to the CLASSPATHs of the Hadoop driver and tasks. Corresponds to the JSON property `jarFileUris` @return [Array<String>]

logging_config[RW]

The runtime logging config of the job. Corresponds to the JSON property `loggingConfig` @return [Google::Apis::DataprocV1::LoggingConfig]

main_class[RW]

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. Corresponds to the JSON property `mainClass` @return [String]

main_jar_file_uri[RW]

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' Corresponds to the JSON property `mainJarFileUri` @return [String]

properties[RW]

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. Corresponds to the JSON property `properties` @return [Hash<String,String>]
