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

             Summary: Publish jars against hadoop 1 (default) too
                 Key: SPARK-7870
                 URL: https://issues.apache.org/jira/browse/SPARK-7870
             Project: Spark
          Issue Type: Bug
          Components: Build
    Affects Versions: 1.3.2, 1.4.0
            Reporter: Andy Petrella


The published jars were always (or at least since 1.1.0, see SPARK-3764) published using hadoop 2 binaries.

However, the default are hadoop 1. Which means that an application that doesn't use hdfs will fail at simple functions like `saveAsObjectFile` (since it uses hadoop interfaces).

There are a couple of points that can be considered wrong here:
* it's not well stated that the published binaries aren't what you can expect base on spark rules w.r.t hadoop 1.0.4
* if an application doesn't need hdfs, the dev couldn't rely on public libraries, but he has to build it's own set without asking for a specific hadoop version (hence will get the 1.0.4) and deploy it on his own :-/
