OutputWriterFactory

abstract class OutputWriterFactory extends Serializable

A factory that produces OutputWriters. A new OutputWriterFactory is created on driver side for each write job issued when writing to a HadoopFsRelation, and then gets serialized to executor side to create actual OutputWriters on the fly.

Instance Constructors

Abstract Value Members

  1. abstract def getFileExtension(context: TaskAttemptContext): String

    Returns the file extension to be used when writing files out.

  2. abstract def newInstance(path: String, dataSchema: StructType, context: TaskAttemptContext): OutputWriter

    When writing to a HadoopFsRelation, this method gets called by each task on executor side to instantiate new OutputWriters.

    path

    Path to write the file.

    dataSchema

    Schema of the rows to be written. Partition columns are not included in the schema if the relation being written is partitioned.

    context

    The Hadoop MapReduce task context.
