Subject RE: can one map instance handle many data of input paths at the same time
Date Thu, 20 Jan 2011 15:35:09 GMT
First a caveat... I'm going from memory and I haven't had my first cup of coffee yet... :-)

The answer is it depends.
If your input is a directory, then I believe that you will pick up all of the files in the
directory.
If you are trying to specify just two files... I don't believe so.

(Now watch. I'm wrong and I do need to get more sleep.)

Subject: can one map instance handle many data of input paths at the same time

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,
