HBase启动错误提示别的机器60000已经存在
已经用cm 安装好了cdh，需要在上面添加HBase，并且做一个HBase故障转移功能，现在需要配置2个HMaster 在不同的机器上。
启动出现异常信息：

错误原因：
在日志找到错误日志信息：

错误新日志：

以上2个错误都用同一个办法解决
解决办法：
hadoop fs -mkdir /hbase hadoop fs -chmod 777 /hbase hadoop fs -chown hbase:hbase /hbase

解决办法：
1.切换到zookeeper的bin目录；
2.执行$sh zkCli.sh
输入 ls /
4.输入rmr /hbase
5、重启zk，重启 hbase即可
