Zhong Yanghong commented on KYLIN-3388:
---------------------------------------
To deal with this issue, there're two ways:
* Disable the distribute by feature, by setting
kylin.source.hive.redistribute-flat-table=false
* Use distribute by multiple columns rather than by rand(), which needs a patch.
> Data may become not correct if mappers fail during the cube building step,
> "distribute by rand()"
