Hi,
I have an existing enterprise system using web services. I'd like to have an
event in the web service eventually result in a map/reduce being performed. It
would be very desirable to be able to package up the map reduce classes into a
jar that gets deployed inside the war file for the web service. (Primarily
just to make redeployment easy.) In effect, I believe what I'm asking is if
there is a way I can stream the map/reduce code (ie, the jar file) down to the
JobTracker.
Could someone please confirm whether I can do this or not, and if I can, help
point me in the right direction?
Thanks in advance for any insight...
You could embed the JAR in the WAR as a single resource, stream it out
from there to the filesystem and then upload it. As a feature creep, you
could see if the the copy operations handled jar: as a filesystem URI
which would then enable a streamed upload.
