Subject Re: Question of Bookkeeper about "static final String BOOKIE_REGISTRATION_PATH = "/ledgers/available/"
Date Wed, 21 Dec 2011 10:20:37 GMT
Ah, this is an omission in the doc. You need to create /ledgers & /ledgers/available in
zookeeper before running the cluster.

To do this, do
bin/bookkeeper org.apache.zookeeper.ZooKeeperMain -server sb052:2181 create /ledgers 0
bin/bookkeeper org.apache.zookeeper.ZooKeeperMain -server sb052:2181 create /ledgers/available
0
