RDD saveAsTextFile() to local disk

[Vijay Pawnarkar <vi...@gmail.com>]

Getting exception when wrting RDD to local disk using following function

 saveAsTextFile("file:////home/someuser/dir2/testupload/20150708/")

The dir (/home/someuser/dir2/testupload/) was created before running the
job. The error message is misleading.


org.apache.spark.SparkException: Job aborted due to stage failure: Task 0
