Shaofeng SHI commented on KYLIN-3388:
-------------------------------------
Before a hot-fix for this is released, we recommend you disable the
redistribution feature to ensure data's accuracy, by setting:
kylin.source.hive.redistribute-flat-table=false
in conf/kylin.properties. A restart is needed to take effect.
> Data may become not correct if mappers fail during the redistribute step,
> "distribute by rand()"
