HBase:/ hbase/meta-region-server节点不存在

Question

我已经安装了cloudera和hdfs,mapreduce,zookeper,hbase.有这些服务的4个节点(3个zookeeper).所有都是由cloudera向导安装的,在cloudera中没有配置问题.从java连接我有一个错误:

有任何想法吗？

我试图通过客户端0.96连接到HBase 0.94.根据https://blog.cloudera.com/blog/2013/10/what-are-hbase-znodes/ znode/hbase/root-region-server在/ hbase/meta-region-server中替换为0.96, java客户端无法找到.
