问题描述
我已经在上面安装了 cloudera 和 hdfs、mapreduce、zookeper、hbase.具有这些服务的 4 个节点(3 个动物园管理员).所有都由 cloudera 向导安装，并且在 cloudera 中没有配置问题.从 java 连接时出现错误:
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:

有什么想法吗?
推荐答案
我曾尝试通过客户端 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 0.96 中被/hbase/meta-region-server 替换，java 客户端无法找到.
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.
