解决方案：
其实原因在就两条

Caused by: org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hbase.TableExistsException): kylin_metadata

Caused by: org.apache.hadoop.hbase.TableExistsException: kylin_metadata

删除HBase中的 kylin_metadata，删除zookeeper中的kylin_metadata节点，重新启动就OK了。

zookeeper:

rmr /kylin/kylin_metadata
