### Question:
ZookeeperClusterStatus extends ClusterStatus { @Override public boolean isEnabled(boolean useCache, String cluster, String table) { if (useCache) { Boolean e = _enabled.get(getClusterTableKey(cluster, table)); if (e != null) { return e; } } long s = System.nanoTime(); String tablePathIsEnabled = ZookeeperPathConstants.getTableEnabledPath(cluster, table); try { checkIfOpen(); if (_zk.exists(tablePathIsEnabled, false) == null) { return false; } } catch (KeeperException e) { throw new RuntimeException(e); } catch (InterruptedException e) { throw new RuntimeException(e); } finally { long e = System.nanoTime(); LOG.debug("trace isEnabled took [" + (e - s) / 1000000.0 + " ms]"); } return true; } ZookeeperClusterStatus(ZooKeeper zooKeeper);  ZookeeperClusterStatus(String connectionStr); @Override List<String> getClusterList(boolean useCache); @Override List<String> getControllerServerList(); @Override List<String> getOnlineShardServers(boolean useCache, String cluster); @Override List<String> getShardServerList(String cluster); @Override boolean exists(boolean useCache, String cluster, String table); @Override boolean isEnabled(boolean useCache, String cluster, String table); @Override TableDescriptor getTableDescriptor(boolean useCache, String cluster, String table); @Override List<String> getTableList(boolean useCache, String cluster); void close(); @Override String getCluster(boolean useCache, String table); @Override boolean isInSafeMode(boolean useCache, String cluster); @Override int getShardCount(boolean useCache, String cluster, String table); @Override Set<String> getBlockCacheFileTypes(String cluster, String table); @Override boolean isBlockCacheEnabled(String cluster, String table); @Override boolean isReadOnly(boolean useCache, String cluster, String table); @Override void createTable(TableDescriptor tableDescriptor); @Override void disableTable(String cluster, String table); @Override void enableTable(String cluster, String table); @Override void removeTable(String cluster, String table, boolean deleteIndexFiles); @Override boolean isOpen();  }### Answer:
@Test public void testIsEnabledNoTable() { assertFalse(clusterStatus.isEnabled(false, DEFAULT, "notable")); assertFalse(clusterStatus.isEnabled(true, DEFAULT, "notable")); }
