Hi,
In my env(HDP3.1 with Hive3, the same as your env), I test hive -e "use default; set mapreduce.job.reduces=1;", and it didn’t throw any error. And maybe you can modify the configuration of your Hive conf.
And if you cannot fix it at Hive side, you can just use “kylin.source.hive.redistribute-flat-table” to skip step2, I think it should work(but not a good practice).

----------------
Best wishes,
Xiaoxiang Yu
