我正在尝试用hadoop ha设置hbase ha。我已经设置了hadoop ha setup并进行了测试。
但是在hbase设置中，启动时，我收到以下错误

我认为我的hbase设置无法识别我的名字服务hdfs-nameservice。
我正在使用Hbase 1.2.4＆amp; Hadoop 2.7.3。
我的hbase-site.xml有
<property>
<name>hbase.rootdir</name>
<value>hdfs://hdfs-nameservice/hbase</value>
</property>
core-site.xml有
<property>
<name>fs.defaultFS</name>
<value>hdfs://hdfs-nameservice:8020</value>
</property>
和hdfs-site.xml有
<property>
<name>dfs.nameservices</name>
<value>hdfs-nameservice</value>
</property>
<property>
<name>dfs.ha.namenodes.hdfs-nameservice</name>
<value>namenode1,namenode2</value>
</property>
//with rpc, http address confs for both namenode1&2
尝试： 1.在hbase conf目录中复制核心和hdfs-site xmls。 2.在环境变量和hbase-env.sh
中添加了Hadoop conf路径仍然无法弄清楚如何让我的hbase识别hdfs-nameservice。
非常感谢任何帮助。
