Can we set or modify number of reducers



We all know to set or modify mappers using NUM mappers is there is way to set or modify number of reducers


From your question, there is no option to modify reducer in sqoop and moreover there is no reducer action in sqoop.



ok zero reducer in sqoop . only map process will run

apart from sqoop can we set number of reducers??


Apart from sqoop:

In Hive

SET mapreduce.job.reduces = -1 (default) (Modify the value as required)


job.setNumReduceTasks(0); (Modify the value as required)


Sqoop jobs are map only. There is no role for reducers.
