# The Hadoop command script

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