Hi Xenia,
I think there is some problem with Zookeeper. Can you make sure that Zookeeper
server is running. If it is running then is it on port 22181? (because your
Giraph job is trying to connect on this port). If Zookeeper is running on some
different port then try running your Giraph job with -Dgiraph.zkList=<zookeper
server ip>:<zookeeper port>
I'm not sure whether you have to start an instance of zookeeper separately or
Giraph will start one for you, I have a separate instance running on my cluster
and I specify the server and port via -Dgiraph.zkList option.
I hope that works.
Vivek

Subject: giraph 1.1.0 Execution Error
Hi experts,
I try to execute Giraph 1.1.0 on a small cluster but I have the
following Errors:

However Giraph 1.0.0 version run without any problems.
What might be the solution for the above errors?
Any help is appreciated.
Thanks
