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

             Summary: Rdds could be different between orginal one and 
save-out-then-read-in one
                 Key: SPARK-11722
                 URL: https://issues.apache.org/jira/browse/SPARK-11722
             Project: Spark
          Issue Type: Bug
          Components: PySpark
    Affects Versions: 1.5.1
         Environment: redhat6.4  64bit;   standalone-cluster ; 3 machines
            Reporter: liangguoning


I found a bug on pyspark;
I did some operations to create a rdd  A,  but I found the data are different 
between that orginal A  and the saved_to_hdfs's  one, called B,
I also printed all detail data inside my function and discovered that A indeed 
contains a different one record from B.
That record causes a different result under the same functions. 
I got B  through 2 methods : A.saveAsTextFile  and  sc.textFile
I also check the raw data, and found that B is the right rdd. 
---
I tried another A2 through sc.parallelize(A.collect()) and got the same result 
as A.
Thanks
