No. There isn't *any* version of Hadoop with a (stable) append command.

Thanks, Bryan. Does 0.18.3 has built-in "append" command?

I believe the last word on appends right now is that the patch that was committed broke a lot of other things, so it's been disabled. As such, there
is no working append in HDFS, and certainly not in hadoop-17.x.

what about an identity mapper taking A and B as inputs?  this will
likely mix rows of A and B together though...

I need to append file A to file B in HDFS without
downloading/uploading
them to
local disk. Is there a way?
