Title: Change the order of CLASSPATH.

SPARK_TOOLS_JAR should be placed after CLASSPATH or at least after SPARK_CLASSPATH.

If SPARK_TOOLS_JAR is placed before CLASSPATH, all assembled classes and resources in spark-tools-assembly.jar beat those in CLASSPATH or SPARK_CLASSPATH, which might be replaced by customized versions.
