          Description

          Create a new mechanism to suppress the warning about HADOOP_HOME deprecation.

          I'll create a HADOOP_HOME_WARN_SUPPRESS environment variable that suppresses the warning.

              Warning should go to stderr. If this env is not used outside of bin/hadoop, unset it.

              The warn patch for 20-security adds the suppression and redirects it to stderr.

              The 204/205 patch removes the warning.

              Did you set HADOOP_HOME_WARN_SUPPRESS in your environment?

              Owen, it's probably too late on asking this but we could have put the warning check AFTER 

                . "${HADOOP_CONF_DIR}/hadoop-env.sh"

              so that people can set HADOOP_HOME_WARN_SUPPRESS inside the config?
