lets see the minimal query that shows your problem with some comments about
cardinality of the tables in the join. maybe there could be a crude
workaround using a temp table or some such device if nothing jumps out at
us.

I am trying to optimize a hive join query, I have a join of two big tables. The
join between them is taking too long, no matter how many reducers I set, there
are always two reducers struggling to finish in the end of the job
The job not always ends, sometime it fails with memory prob
