在配置HBase的Kerberos认证过程中遇到HMaster启动失败的问题，随后尝试修改zookeeper配置时又出现新的错误提示。疑似由于Zookeeper集群配置不当导致。

在配置hbase的kerberos认证时，启动zookeeper之后，启动hbase出现如下错误，导致HMaster立马down掉

但是接着在zkEnv.sh中配置了如下内容之后，

SERVER_JVMFLAGS="-Dsun.net.spi.nameservice.provider.1=dns,sun"

启动zookeeper出现了如下错误：

2016-04-29 13:37:43,284 [myid:] - ERROR [main:ZooKeeperServerMain@63] - Unexpected exception, exiting abnormally
java.io.IOException: Could not configure server because SASL configuration did not allow the  ZooKeeper server to authenticate itself properly: javax.security.auth.login.LoginException: mj1.bdsm.cmcc

可能是因为zookeeper需要多个结点的问题。未完待续
