[jira] [Created] (SPARK-2242) Running sc.parallelize(..).count() hangs pyspark

Xiangrui Meng created SPARK-2242:
------------------------------------

             Summary: Running sc.parallelize(..).count() hangs pyspark
                 Key: SPARK-2242
                 URL: https://issues.apache.org/jira/browse/SPARK-2242
             Project: Spark
          Issue Type: Bug
          Components: PySpark
    Affects Versions: 1.1.0
            Reporter: Xiangrui Meng
            Priority: Critical


Running the following code hangs pyspark in a shell:

{code}
sc.parallelize(range(100), 100).count()
{code}

It happens in the master branch, but not branch-1.0. And it seems that it only happens in a pyspark shell. [~andrewor14] helped confirm this bug.
