最近在学习hbase，按照教程配置好后，发现使用hbase-daemon.sh start master 启动后，HMaster进程一会自动退出，查看日志如下：

请高手看看是什么原因，在网上找了很多解决办法，但还是无法解决。
找到一个同样问题，供你参考下：http://blog.chinaunix.net/uid-26275986-id-4008535.html
一、启动HBase
在Namenode节点上执行start-hbase.sh后，HMaster启动了，但是过几秒钟就挂了，
查看日志报错：
[master:master:60000] catalog.CatalogTracker: Failed verificat......
答案就在这里：Hbase HMaster启动问题
