Are you saying that basically MRv1 is deprecated/unsupported at this point as far as the Apache folks are concerned? In that case, I should take the issue up with Cloudera if/once we have a support contract :) > > Please also note, that MRv1 as delivered by CDH4 distribution is completely > different from the code that exists in trunk/branch-2. > That doesn't bother me as it doesn't affect what I am working on :) I care about someone breaking this interface for no reason. I could understand it if MRv1 was no longer supported by Apache or Cloudera, but that appears to not be that case from what I can tell. So in my mind it's just a bug. > > So far the HDFS bits seem to work fine under daemontools-encore; I have > > been using it for several months now without problems. > > Great!

Then I checked the Apache repo and saw that it was broken there, too, hence my email. At any rate, once I have the scripts in working order I will send an update.
