HBaseTestingUtility與MiniCluster一起工作嗎？

Question

我有一個簡單的單元測試，我想對HBaseTestingUtility MiniCluster運行。缺少使用HBaseTestingUtility運行測試所需的傳遞依賴關係。我一直在追查NoClassDefFoundErrors，並且遇到了其中一個jar文件的打包錯誤。這裏的錯誤：

java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/test/MetricsAssertHelper at org.apache.hadoop.hbase.MiniHBaseCluster.<init>(MiniHBaseCluster.java:91)

當我在我的項目的.jar文件搜索MetricsAssertHelper我找到META-INF/services目錄下的該文件：

jar tvf org/apache/hbase/hbase-hadoop2-compat/1.0.0/hbase-hadoop2-compat-1.0.0-tests.jar | grep MetricsAssertHelper 53 Sat Feb 14 19:43:40 MST 2015 META-INF/services/org.apache.hadoop.hbase.test.MetricsAssertHelper 1337 Sat Feb 14 19:43:40 MST 2015 org/apache/hadoop/hbase/test/MetricsAssertHelperImpl$MockMetricsBuilder.class 3743 Sat Feb 14 19:43:40 MST 2015 org/apache/hadoop/hbase/test/MetricsAssertHelperImpl$MockRecordBuilder.class 6689 Sat Feb 14 19:43:40 MST 2015 org/apache/hadoop/hbase/test/MetricsAssertHelperImpl.class

這是不是.class文件，但是。我想知道是否從.jar文件中缺少MetricsAssertHelper.class文件，因爲那裏有一個'MetricsAssertHelperImpl.class文件'。

這是我的代碼和mvn依賴關係。錯誤發生在HBaseTestingUtility.startMiniCluster()調用上。

private static HBaseTestingUtility utility; 

@Before 
public void setUp() throws Exception { 
    utility = new HBaseTestingUtility(); 
    utility.startMiniCluster(); 
}

問題是，我還需要依賴於hbase-hadoop-compat除了hbase-hadoop2-compat。以下是使用HBaseTestingUtility MiniCluster運行JUnit測試所需的依賴關係的完整列表。
