在自己的机器上操作的，之前因为网络出问题强行关闭虚拟机。再次开启时发现HMaster进程启动不了（HRegionServer正常启动，而HMaster启动几秒后挂了），查看日志发现如下：

关键信息

meta数据出问题了.
打开hdfs webUI发现：
有数据丢失了。。。
参考这位大佬博客：https://www.cnblogs.com/yueweimian/p/6183264.html
因为不是生产环境，干脆一点就把HBase在hdfs上的数据全部删除了，若删错了可以从trash中找回来（若配置了trash）。。。
#我电脑上配置的hbase元数据存储路径为hdfs://chdp11:9000/hbase
hadoop fs -rm -r /hbase #删库警告
重新启动，问题解决，但hbase数据全部丢失，因为是学习环境所以也就没什么的了，没必要花太多的时间去恢复不重要的数据。
