Hi wang, "DISTRIBUTE BY RAND()" may cause data inconsistency, so we changed it to distribute by the first few columns of the rowkey, and the default is the first 3 columns. You can see the following issues for more details. If you don't have a data skew problem, you can just disable the "redistribute" step by setting "kylin.source.hive.redistribute-flat-table" to false. https://issues.apache.org/jira/browse/KYLIN-3388 https://issues.apache.org/jira/browse/KYLIN-3457
