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

             Summary: IllegalArgumentException when writing to disk
                 Key: SPARK-1353
                 URL: https://issues.apache.org/jira/browse/SPARK-1353
             Project: Apache Spark
          Issue Type: Bug
          Components: Block Manager
         Environment: AWS EMR 3.2.30-49.59.amzn1.x86_64 #1 SMP  x86_64 GNU/Linux
            Reporter: Jim Blomo
            Priority: Minor


The Executor may fail when trying to mmap a file bigger than Integer.MAX_VALUE 
due to the constraints of FileChannel.map 
(http://docs.oracle.com/javase/7/docs/api/java/nio/channels/FileChannel.html#map(java.nio.channels.FileChannel.MapMode,
 long, long)).  The signature takes longs, but the size value must be less than 
MAX_VALUE.  This manifests with the following backtrace:

java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE
