@rem The Hadoop command script
@rem
@rem Environment Variables
@rem
@rem JAVA_HOME The java implementation to use. Overrides JAVA_HOME.
@rem
@rem YARN_CLASSPATH Extra Java CLASSPATH entries.
@rem
@rem YARN_HEAPSIZE The maximum amount of heap to use, in MB.
@rem Default is 1000.
@rem
@rem YARN_{COMMAND}_HEAPSIZE overrides YARN_HEAPSIZE for a given command
@rem eg YARN_NODEMANAGER_HEAPSIZE sets the heap
@rem size for the NodeManager. If you set the
@rem heap size in YARN_{COMMAND}_OPTS or YARN_OPTS
@rem they take precedence.
@rem
@rem YARN_OPTS Extra Java runtime options.
@rem
@rem YARN_CLIENT_OPTS when the respective command is run.
@rem YARN_{COMMAND}_OPTS etc YARN_NODEMANAGER_OPTS applies to NodeManager
@rem for e.g. YARN_CLIENT_OPTS applies to
@rem more than one command (fs, dfs, fsck,
@rem dfsadmin etc)
@rem
@rem YARN_CONF_DIR Alternate conf dir. Default is ${HADOOP_YARN_HOME}/conf.
@rem
@rem YARN_ROOT_LOGGER The root appender. Default is INFO,console
