Hi Dongjin,
Are you available for chat sometime this week? I'm trying to figure out how
this diff relates to GIRAPH-1068. There we removed an option to start multiple
zookeepers from the giraph itself. It is still possible to connect to external
zookeeper quorum though.
To understand what needs to be done here, can you explain your use case? If I
understand correctly, here you create 5 zookeeper instances from the Giraph
job. What is the reason, and why don't you use single zookeper?

> We are running job with quorum of 3 zookeepers. Each serves has got long name
> (turing452.fi.callan.de:22181). Connection strings are stored to Hadoop
> Counters (for example:
> turing452.fi.callan.de:22181,turing124.fi.callan.de:22181,turing488.fi.callan.de:22181)
> but since name of counter is limited to ~63 character the connection string
> is trimmed (turing452.fi.callan.de:22181,turing124.fi.callan.de:22181,turin).
