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

             Summary: No option for AM native library path in yarn-client mode.
                 Key: SPARK-7281
                 URL: https://issues.apache.org/jira/browse/SPARK-7281
             Project: Spark
          Issue Type: Bug
          Components: YARN
    Affects Versions: 1.3.1, 1.4.0
            Reporter: Marcelo Vanzin
            Priority: Minor


There are many options to control the AM in yarn-client mode, but the option for the native library path is missing. Without that, users have to change the process's environment directly (using {{spark.yarn.appMasterEnv.LD_LIBRARY_PATH}} on Linux, for example) to add things to the native library path.

Depending on the cluster's configuration, native libraries are needed in the AM (for example when using the JNI-based group mapper in Hadoop).

There's also no option to control the AM's classpath, but since the AM is not running user code, that seems less important.
