During sqoop incremental import, upfront we may not know how may records added / modified.
After execution, the mapper output are not evenly distributed.
Will you be able to provide tips to mention the ideal number of mapper and to distribute records evenly across mapper.
Sample have given two mapper details
file size 47 MB - duration time 27 sec CPU time 14670 ms = 0.2445 Minutes
file size 188 MB - duration time 42 mins CPU time 41600 ms = 0.6933 Minutes
Thanks in advance.
