How to set the no of mappers? I am running a job with input file of 5000 records.but actually it is a small file for hadoop..but i need to know whether it can be exceuted faster.
when i tried to run my job it took nearly 30 min to complete my job... why so? If i set my mappers to a lower count whether any reflection happens to my job performance? -- *Thanks & Regards* Unmesha Sreeveni U.B *Junior Developer*
