org.apache.zookeeper.ClientCnxn: Opening socket connection to server localhost/127.0.0.1:218
在vmware中安装hadoop伪分布式，使用host-only模式使用hbase shell一直正常，后来为了能上网改为了Briged模式。
启动后再命令端看到了关于hbase的异常信息org.apache.zookeeper.ClientCnxn: Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to authenticate using SASL (Unable to locate a login configuration)认为是hbase的错误
一直找不出原因，上网也搜了，有的说是hbase-site.xml的zookeeper的配置，有的说是时钟不一致。唉，又是没好好看日志的原因，原来是hadoop的datanode没启动起来。
datanode失败的原因是旧的namespaceID和namenode格式化的不一致。
总结：好好看日志分析原因，对于新手操作后一定要检查操作达到目的，如可以使用jps检查进程是否启动。
