---------------------------------------

             Summary: Streaming | Setting checkpoint as a local directory 
results in Checkpoint RDD has different partitions error
                 Key: SPARK-4862
                 URL: https://issues.apache.org/jira/browse/SPARK-4862
             Project: Spark
          Issue Type: Bug
          Components: Streaming
    Affects Versions: 1.1.1, 1.1.0
            Reporter: Aniket Bhatnagar
            Priority: Minor


If the checkpoint is set as a local filesystem directory, it results in weird 
error messages like the following:

org.apache.spark.SparkException: Checkpoint RDD CheckpointRDD[467] at apply at 
List.scala:318(0) has different number of partitions than original RDD 
MapPartitionsRDD[461] at mapPartitions at StateDStream.scala:71(56)

It would be great if Spark could output better error message that better hints 
at what could have gone wrong.
