Subject Re: Zookeeper problem when running in Pure Yarn
Date Fri, 26 Jul 2013 21:13:57 GMT
Its buried in the middle of the stack trace :) sorry my bad!

You need to launch your own standalone Zookeeper instance or quorum, when
the YARN port is better integrated into mainline Giraph the plan is for
Zookeeper to be launched in its own process at the Application Master
instead of within Giraph, so we don't integrate it currently. If you don't
supply your own instance or quorum before the job run to connect to, Giraph
on YARN doesn't launch one.
