There is somewhat less need for this at this point since files appear

Hi,
Is there any lock service in hadoop to sync the access to file (such

details posted by Jason below) and saw Jason's email in the archive, but

Hello Dennis, Ted and Christophe.
I had, as a precaution, built my jar so that the lib/ directory
contained both the actual jars AND the jars unzipped, i.e:
lib/:
foo.jar
foo2.jar
foo3.jar

foo2/
Just to cover as much ground as possible.

you're getting caught anywhere and not sure why.

or a Map/Reduce cluster that's been started outside the HOD provisioning
