pyspark.RDD.saveAsNewAPIHadoopFile

RDD.saveAsNewAPIHadoopFile(path: str, outputFormatClass: str, keyClass: Optional[str] = None, valueClass: Optional[str] = None, keyConverter: Optional[str] = None, valueConverter: Optional[str] = None, conf: Optional[Dict[str, str]] = None) → None

Output a Python RDD of key-value pairs (of form RDD[(K, V)]) to any Hadoop file system, using the new Hadoop OutputFormat API (mapreduce package). Key and value types will be inferred if not specified. Keys and values are converted for output using either user specified converters or “org.apache.spark.api.python.JavaToWritableConverter”. The conf is applied on top of the base Hadoop conf associated with the SparkContext of this RDD to create a merged Hadoop MapReduce job configuration for saving the data.
