  2. Hi,

    I have a map-only job and cannot control the number of mappers as it depends on the number of input splits. Can you please let me know if there is any way to customize the name of the output file. I’m trying to

    1. Generate just one output file from a mapper and
    2. Customize the name of the output file to remove -m-0000 completely.

    Thanks.
