Subject Re: FileNotFoundException: File _bsp/_defaultZkManagerDir/job_201308291126_0029/_zkServer does not exist.

can you try defining the zookeeper manager directory from the command line?
like this -D giraph.zkManagerDirectory=/path/in/hdfs/foobar

you'll have to delete this directory by hand before each job. Just to see
if it solves the problem. Then I could know how to fix it.
