Rakesh R commented on BOOKKEEPER-255:
-------------------------------------
Here I feel the problem is, when we do NN formatting its going to intialize the
configured BKJM journals and trying to create the BookKeeper client, this
inturn reading the available Bookies.
BK client looks for the available Bookie servers from ZK and is throwing
exception.

bk.getZkHandle().getChildren("/ledgers/available", this, callback, null);

> BKJM : Namenode format fails, if there is no BK root
