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

             Summary: Spark JAR compiled with Java 7 leads to PySpark not work 
in YARN
                 Key: SPARK-1920
                 URL: https://issues.apache.org/jira/browse/SPARK-1920
             Project: Spark
          Issue Type: Bug
          Components: PySpark, YARN
    Affects Versions: 1.0.0
            Reporter: Tathagata Das


Current (Spark 1.0) implementation of PySpark on Yarn requires python to be 
able to read Spark assembly JAR. But Spark assembly JAR compiled with Java 7 
can sometimes be not readable by python. This can be due to the fact that JARs 
created by Java 7 with more 2^16 files is encoded in Zip64, which python cant 
read. 

[SPARK-1911|https://issues.apache.org/jira/browse/SPARK-1911] warns users from 
using Java 7 when creating Spark distribution. 

One way to fix this is to put pyspark in a different smaller JAR than rest of 
Spark so that it is readable by python.
