> There are thousands of cubes in didi,  so in order to cut the metadata we have 4 kylin clusters. They use 1 hdfs cluster, 1 hive database, and 1 hbase cluster.
> KYLIN_INTERMEDIATE_PREFIX is set by MetadataConstants. In order to the unused intermediate table can be properly cleaned up by cleanTool,  the intermediate table prefix needs to be set differently by kylin config.
> kylin config  add kylin.source.hive.intermediate-table-prefix， default 'kylin_intermediate_'.
