Yes. What you're looking for is TextInputFormat.addPath() (assuming
you're
talking about text). You can call this multiple times and add
multiple input
paths if they are all of the same data format (i.e. text). If you have
multiple paths that contain different format data, you'll need to use
MultipleInputs. See the javadoc for details on usage.

There are two input paths, example: /user/test1/ and /user/test2/
path.
Can
one map instance handle many data of input paths at the same time?


Thanks,

LiuLei

    If you meant a single Mapper instance reading files/splits from those
    two sources, it should be doable too.
