Ah, never mind, I found the jar command in the java-1.7.0-openjdk-devel package. I only had java-1.7.0-openjdk installed. Looks like I just need to install java-1.7.0-openjdk-devel then set JAVA_HOME to /usr/lib/jvm/java instead of /usr/lib/jvm/jre.

Is this an issue anybody else has run into? Would it be possible to use the unzip command instead? The fact that $JAVA_HOME/bin/jar is missing also breaks the check that ensures that Spark was built with a compatible version of java to the one being used to launch spark. The unzip tool of course wouldn't work for this, but there's probably another easy alternative to $JAVA_HOME/bin/jar. ~ Jonathan Kelly
