Lee Dongjin commented on GIRAPH-882:
------------------------------------
[~edunov] As you told in the previous comment, the option to start multiple
zookeepers from giraph itself was removed from GIRAPH-1068. Yes, it is right.
But it is also possible to use *external* zookeeper quorum. Because of that, we
need to worry about *external* multiple zookeepers, and it is what I would like
to solve exactly. (A single host with a long name is out of my interest.)
> List of zookeeper connection strings is trimmed by Hadoop counters.

> 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).
