-`SPARK_YARN_JAR` is deployed for running executor, this could be a local path or HDFS. HDFS allows YARN to cache it on nodes so that it doesn't need to be distributed each time an application runs. To point to a jar on HDFS, for example, set this configuration to "hdfs:///some/path".

 `HADOOP_CONF_DIR` should contains yarn-site.xml and core-site.xml.
