Koji Noguchi commented on HADOOP-6284:
--------------------------------------
bq. How about we add a HADOOP_JVM_OPTS?
I only want this set for 'JAVA_PLATFORM=`CLASSPATH... ${JAVA}' command.
(Since UsePerfData looks required for java tools to connect to jvm.)
HADOOP_JVM_OPTS sounds too general for that.
> Any hadoop commands crashing jvm (SIGBUS) when /tmp (tmpfs) is full
