Allen Wittenauer commented on YARN-6691:
----------------------------------------
{code}
+# Specify the max heapsize for the Router. If no units are
+# given, it will be assumed to be in MB.
+# This value will be overridden by an Xmx setting specified in either
+# HADOOP_OPTS and/or YARN_ROUTER_OPTS.
+# Default is the same as HADOOP_HEAPSIZE_MAX.
+#export YARN_ROUTER_HEAPSIZE=
+
{code}
The \_HEAPSIZE vars are only used for backward compatibility. All new daemons
in 3.x use _OPTS to set heap.
