> There are two places that checks environment variable (HADOO_CONF_DIR or YARN_CONF_DIR).
> It's better to extract one method to avoid code duplication.
> {code:java}
> // check if required Hadoop environment variables are set. If not, warn user
> private void checkEnvironmentVariable() {
> if (System.getenv("HADOOP_CONF_DIR") == null &&
> System.getenv("YARN_CONF_DIR") == null) {
> LOG.warn("Neither the HADOOP_CONF_DIR nor the YARN_CONF_DIR environment variable is set. " +
> "The Flink YARN Client needs one of these to be set to properly load the Hadoop " +
> "configuration for accessing YARN.");
> }
> }
> {code}
