原因描述:遇到了很多kylin启动报错的问题。报错的原因都大差不差，详细的报错见下面具体的报错内容。在之前的项目中hbase配置了很多的内容，kylin可能会和其他的配置有所冲突，所以导致的报错。

具体的报错:

解决方法：

启动报错，说明kylin和hbase发生了冲突，这个时候需要把hbase之前存储的东西都删掉，即可启动kylin

第一步：把hdfs上已经存储的hbase删除掉

替换方案：如果数据重要可以把hbase中的hbase-site.xml修改内容，修改名字即可

<property>
    <name>hbase.rootdir</name>
    <value>hdfs://hadoop102:8020/hbase</value>
  </property>

第二步：删除zk下存储的hbase的节点信息

[root@hadoop102 zookeeper-3.5.7]$ bin/zkCli.sh

[zk: localhost:2181(CONNECTED) 5] deleteall /hbase

第三步：删除kylin的bin目录下的

[root@hadoop102 bin]$ rm -rf cached-*
