Tathagata Das created SPARK-1920: ------------------------------------ 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
