 2. Load environment configuration by running `source $INSTALL_PREFIX/greenplum_path.sh`.
 3. Load hdfs configuration. For example, `export HADOOP_HOME=/Users/wuhong/hadoop-2.7.2 && export PATH=${PATH}:${HADOOP_HOME}/bin`. Since some test cases need `hdfs` and `hadoop` command, just ensure these commands work before running. Otherwise you will get failure.
