    Hadoop must be in your path for hive executable to work.
    After installation, set $HIVE_HOME in your profile:
      export HIVE_HOME=#{libexec}

    If you want to use HCatalog with Pig, set $HCAT_HOME in your profile:
      export HCAT_HOME=#{libexec}/hcatalog

    You may need to set JAVA_HOME:
      export JAVA_HOME="$(/usr/libexec/java_home)"
