搭建kylin，报2181错误

在启动kylin的时候，需要以下步骤，缺一不可

start-all.sh

zkServer.sh start

hbase-start.sh

hive --service metastore &
hive --service hiveserver2 &
mr-jobhistory-daemon.sh start historyserver

kylin.sh start

突然报2181错误

其实查看我们会发现是hbase的hbse-site.xml需要调整一下

进入hbase的conf中的hbase-site.xml

把原先的内容

  
              hbase.zookeeper.quorum
             node01:2181,note02:2181,note03:2181
 

更改成

  
         hbase.zookeeper.property.clientPort
         2181
        

     
         hbase.zookeeper.quorum
         note01,note02,note03
    

然后我们再次启动kylin

kylin.sh start

 成功了！

kylin真的是最需要前面环境的软件，需要hdfs，hive，hbase，zookeeper，mr才能启动成功。
