# Specify the max heapsize for the ResourceManager. If no units are

|
|
# This value will be overridden by an Xmx setting specified in either

|
# HADOOP_OPTS and/or YARN_RESOURCEMANAGER_OPTS.
|
|
# Default is the same as HADOOP_HEAPSIZE_MAX

# Specify the JVM options to be used when starting the ResourceManager.
