--------------------------------
Summary: Emphasize that jars should be built with Java 6 for YARN
Key: SPARK-1911
URL: https://issues.apache.org/jira/browse/SPARK-1911
Project: Spark
Issue Type: Sub-task
Reporter: Andrew Or
This is especially a big problem especially for PySpark. Currently we warn
users only in make-distribution.sh, but most users build the jars directly. We
should emphasize it in the docs especially for PySpark and YARN because this
issue is not trivial to debug.
