Shivaram Venkataraman commented on SPARK-2075: ---------------------------------------------- [~sunrui] What I can see from this JIRA discussion (and [~srowen] please correct me if I am wrong) is that Hadoop 1 vs. Hadoop 2 is one of the causes of incompatibility. It is _not the only_ reason and I don't think we exactly know why the pre-built binary for 1.1.0 is different from the maven version. I think the best practice advice is to use the exact same jar in the application and in the runtime. Marking Spark a provided dependency in the application build and using spark-submit is one way of achieving this. Or one can publish a local build to maven and use the same local build to start the cluster etc. > Anonymous classes are missing from Spark distribution > ----------------------------------------------------- > > Key: SPARK-2075 > URL: https://issues.apache.org/jira/browse/SPARK-2075 > Project: Spark > Issue Type: Bug > Components: Build, Spark Core > Affects Versions: 1.0.0 > Reporter: Paul R.
