I'm running hive job on 24TB dataset (on 34560 partitions ). here about 500
to 1000 mappers are getting succeded (total of 80000) and rest mappaers are
taking for ever ( their status stays at 0% all times ). Is there any
limitations on number of partitions/dataset ? are there any paraemeters to
Same job is suceeding on 18TB (25920 partitions ).
I already set below in my hive query.
