             Summary: [YARN+Windows] Setting SPARK_YARN_CACHE_FILES exceeds command line length limit on Windows
                 Key: SPARK-14602
                 URL: https://issues.apache.org/jira/browse/SPARK-14602
             Project: Spark
          Issue Type: Bug
          Components: Deploy, Spark Submit, Windows, YARN
    Affects Versions: 2.0.0
         Environment: YARN on Windows
            Reporter: Sebastian Kochman


After change https://issues.apache.org/jira/browse/SPARK-11157, which removed a single large Spark assembly in favor of multiple small jars, when you try to submit a Spark app to YARN on Windows (using spark-submit.cmd), the app fails with the following error:

Diagnostics: The command line has a length of 12046 exceeds maximum allowed length of 8191. Command starts with: @set SPARK_YARN_CACHE_FILES=[...]/.sparkStaging/application_[...] Failing this attempt. Failing the application.

So basically a large number of jars needed for staging in YARN causes exceeding Windows command line length limit.
