配置文件中 加入
hbase.config.hbase.zookeeper.quorum: XXX hbase.config.hbase.zookeeper.property.clientPort: XXXX
因為 pom Hbase引入了Guava 是13 的低版本 如果項目中引入了Guava 高版本的 需要在項目中重寫一個類 Stopwatch

/**
* An object that measures elapsed time in nanoseconds. It is useful to measure
* elapsed time using this class instead of direct calls to {@link
* System#nanoTime} for a few reasons:
* An alternate time source can be substituted, for testing or performance
* reasons.
* As documented by {@code nanoTime}, the value returned has no absolute
* meaning, and can only be interpreted as relative to another timestamp
* returned by {@code nanoTime} at a different time. {@code Stopwatch} is a
* more effective abstraction because it exposes only these relative values,
* not the absolute ones.
* Basic usage:
* <p>
* Stopwatch stopwatch = Stopwatch.{@link #createStarted createStarted}();
* doSomething();
* stopwatch.{@link #stop stop}(); // optional
* long millis = stopwatch.elapsed(MILLISECONDS);
* log.info("time: " + stopwatch); // formatted string like "12.3 ms"
* Stopwatch methods are not idempotent; it is an error to start or stop a
* <p>
* stopwatch that is already in the desired state.
* When testing code that uses this class, use
* <p>
* {@link #createUnstarted(Ticker)} or {@link #createStarted(Ticker)} to
* supply a fake or mock ticker.
* This allows you to
* simulate any valid behavior of the stopwatch.
* Note: This class is not thread-safe.
