> Once HIVE-20823 is committed, we should investigate if it's possible to have compactor write directly to base_x_cZ or delta_x_y_cZ.  
> For query based compaction: can we control location of temp table dir?  We support external temp tables so this may work but we'd need to have non-acid insert create files with {{bucket_xxxxx}} names.
>  
> For MR/Tez/LLAP based (should this be done at all?), need to figure out how retries of tasks will work.  Just like we currently generate an MR job to compact, we should be able to generate a Tez job.
