HBase: / HBase /元区域-服务器节点不存在。

I have installed cloudera and hdfs, mapreduce, zookeper, hbase on it. 4 nodes with these services (3 zookeeper). All are installed by cloudera wizard and have no configuration issues in cloudera. On connect from java I have got an error:

我已经安装了cloudera和hdfs, mapreduce, zookeper, hbase。4个节点与这些服务(3个动物管理员)。所有这些都由cloudera向导安装，在cloudera中没有配置问题。从java连接，我有一个错误:

Any ideas?

什么好主意吗?

I had tryied to connect to HBase 0.94 by client 0.96. And acording to https://blog.cloudera.com/blog/2013/10/what-are-hbase-znodes/ znode /hbase/root-region-server is replaced in 0.96 by /hbase/meta-region-server, that the java client wasn't able to find.

我已经将tryied连接到HBase 0.94，客户端0.96。在0.96的/hbase/meta-region-server中，将会替换为https://blog. cloudera.com/blog/2013/10/what-hbase -znode /hbase/root-region-server，这是java客户端无法找到的。
