Hi all, I put up a patch to add support for 2.0.4 and 2.0.5 but (sadly) have not checked back in to see about its review status. It builds, I know that :)
Chaun it looks like you are using Hadoop-2.0.5-alpha but using our default MapReduce v2 interface. So its a YARN cluster underneath, but your tasks are still hosted in Mapper processes. So. It seems like you need Zookeeper installed and then you'll be on your way. Let us know if you need any more advice etc. On Tue, Jun 25, 2013 at 4:00 PM, Chuan Lei <leich...@gmail.com> wrote: > Hi Avery, > > Thanks for your quick answer. Just for your information.
