--------------------------------------

Thank you, Lee!
I've added one comment to your diff and it looks fine for me otherwise. I'll try using this
patch on our cluster to make sure it works and will post update here.

> 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).
