Enclosing class:

Checkpoint

public static class Checkpoint.CheckpointDir
extends java.lang.Object

Checkpoint dir tree.

SparkPipelineOptions checkpointDir is used as a root directory under which one directory is created for Spark's checkpoint and another for Beam's Spark runner's fault checkpointing needs. Spark's checkpoint relies on Hadoop's FileSystem and is used for Beam as well rather than FileSystem to be consistent with Spark.
