示例1: isEnabledTable
/**
* Go to zookeeper and see if state of table is {@link TableState#ENABLED}.
* @param zkw
* @param tableName
* @return True if table is enabled.
* @throws KeeperException
*/
public static boolean isEnabledTable(final ZooKeeperWatcher zkw,
final String tableName) throws KeeperException {
TableState state = getTableState(zkw, tableName);
// If a table is ENABLED then we are removing table state znode in 0.92
// but in 0.94 we keep it in ENABLED state.
return state == null || state == TableState.ENABLED;
