hbase启动几十秒后，HMaster和HRegionserver自动关闭

Question

采用hbase自带的zookeeper。
hbase-site.xml配置如下：


hbase.rootdir
hdfs://master:9000/hbase
hadoop集群地址



hbase.cluster.distributed
true
是否启动集群模式


hbase.tmp.dir
/root/hbase-1.2.4/tmp


hbase.master #指定hbase集群主控节点
master:60000


hbase.zookeeper.quorum
slave1,slave2,slave3
zookeeper集群主机名列表


hbase-root-master-master.log部分日志如下：

已解决，/etc/hosts配置错误
每台虚拟机上都进行如下配置
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.241.235 master
192.168.241.236 slave1
192.168.241.237 slave2
192.168.241.238 slave3
