我已將hbase-client-jar，hbase-common-jar，metric-core-jar添加到我的Eclipse POM文件中...我無法找到我必須做的更改...請幫助我解決此問題..

Answer 1

我解決了此問題，因為存在問題的原因：java.lang.NoClassDefFoundError：com / yammer / metrics / core / Gauge因此，將metrics-core-2.2.0.jar添加到HADOOP_CLASSPATH不起作用...所以我添加了此jar到HADOOP mapred / lib，hdfs / lib，common / lib文件夾..因此此jar在classpath中可用。
