我已将hbase-client-jar，hbase-common-jar，metric-core-jar添加到我的Eclipse POM文件中...我无法找到我必须做的更改...请帮助我解决此问题..

Answer 1

我解决了此问题，因为存在以下问题:java.lang.NoClassDefFoundError:com / yammer / metrics / core / Gauge
所以，将metrics-core-2.2.0.jar添加到HADOOP_CLASSPATH不起作用...所以我将这个jar添加到了HADOOP mapred / lib，hdfs / lib，common / lib文件夹..因此该jar在类路径中可用。
