  def caveats
    <<~EOS
      Hadoop must be in your path for hive executable to work.

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

  test do
    system bin/"schematool", "-initSchema", "-dbType", "derby"
    assert_match "Hive #{version}", shell_output("#{bin}/hive --version")
  end
