------------------------------------
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.
