hbase启动时遇到class not found 错误

问题描述：

1 当hbase自己运行时，没有问题，可以正常启动

2 当搭建完hadoop环境后，再启动报异常：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/util/HBaseConfTool
Caused by: java.lang.ClassNotFoundException: org.apache.hadoop.hbase.util.HBaseConfTool

解决方法：

在conf/hbase-env.sh文件中增加一行：export HBASE_CLASSPATH=$HBASE_HOME/lib

问题出现的原因，可能是hbase将hadoop的根目录当成自己的根目录了...

不能确定，谁知道为什么了可以留言给我
