> rhive.mrapply
function (tablename, mapperFUN, reducerFUN, mapinput = NULL,
mapoutput = NULL, by = NULL, reduceinput = NULL, reduceoutput = NULL,
mapper_args = NULL, reducer_args = NULL, buffersize = -1L,
verbose = FALSE, hiveclient = rhive.defaults("hiveclient"))
.....
...
..

Plz modify function parameters especially all remains after reducerFUN to be neglectable parameters.

like "rhive.mrapply("weights", map, reduce)" to apply map for all columns.
