java - HBase:/hbase/meta-region-server节点不存在

Question

我在上面安装了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)。全部由cloudera向导安装，在cloudera中没有配置问题。从 Java 连接时出现错误:

有什么想法吗？

我曾尝试通过客户端 0.96 连接到 HBase 0.94。并根据 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。
