java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration] with root cause

在用Java web和hbase连接时，报出来这个错误，一开始我以为是hbase导入的包位置不对，不从build path那里导入，而是从WEB-INF下的lib中导入，尝试了之后结果仍是这个错误

后来我就运行了原来的能成功运行的hbase（java实现的）和hdfs(java实现的）代码，这些都是参照慕课网林子雨大数据教程里提示给的代码，结果hdfs的能成功运行，hbase的运行错误，在命令行jps后，发现显示的不对，显示结果如下：

正常的应该是如下图：

由于暂时不知道怎么改，所以只好重装了一次hbase，命令行输入jps后才能正确显示，待找到正确解决办法再更博，此次博客仅作为暂时错误记录。

更新：

在网上搜了搜关于此类HRegionServer和Hmaster消失的问题，可以参考以下网站;
