NoClassDefFoundError: org/apache/hadoop/hbase/TableNotFoundException

如何解决NoClassDefFoundError: org/apache/hadoop/hbase/TableNotFoundException

我打算使用“hbase.mapreduce.Import”将数据从本地文件导入到 Hbase。 我在 root 上执行了 hbase org.apache.hadoop.hbase.mapreduce.Import News file:///Hbackup/News/ 。

但是，当我检查 Hadoop 容器时，我发现发生了错误。下面是master节点的syslog，和另一个slave节点一样：

不幸的是，我在百度和必应上搜索了这个错误，找不到有用的文章，这是我找到的最相关的一篇： java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/MasterNotRunningException

然后我检查了我的 Hadoop 类路径，Hbase jar 已经存在。

root@master:~# $HADOOP_HOME/bin/hadoop classpath
/usr/tools/hadoop/etc/hadoop:/usr/tools/hadoop/share/hadoop/common/lib/*:/usr/tools/hadoop/share/hadoop/common/*:/usr/tools/hadoop/share/hadoop/hdfs:/usr/tools/hadoop/share/hadoop/hdfs/lib/*:/usr/tools/hadoop/share/hadoop/hdfs/*:/usr/tools/hadoop/share/hadoop/yarn/lib/*:/usr/tools/hadoop/share/hadoop/yarn/*:/usr/tools/hadoop/share/hadoop/mapreduce/lib/*:/usr/tools/hadoop/share/hadoop/mapreduce/*:/usr/tools/hbase-2.3.5/lib/*:/usr/tools/hadoop/contrib/capacity-scheduler/*.jar

另外：

1. 以下是版本：

   JDK：1.8.0.291 动物园管理员：3.4.12 Hadoop：2.7.1 Hbase：2.3.5

2. 我发现另一个java程序可以写Hbase，所以我相信Hbase是有效的。

现在我不知道这个错误，我应该怎么做才能解决这个问题？ 感谢您的阅读和回答。
