@Before
  public void setup() throws Exception {
    long now = System.currentTimeMillis() / 1000;
    startTime = 0;

  }
This can't use TestHCatClient because it has to have control over certain conf variables when
the metastore is started.  Plus, we don't need a metastore running in another thread.  The
local one is fine.
