I have a Flume service installed on 3 different hosts (meaning it uses the
same configuration settings). So, service flume1 has 3 instances.
The first instance, which is installed on the same system as the zookeeper
service, connects to my Hbase instance as expected.
The other two instances on the other hosts keeps on trying to connect to
0.0.0.0:2181 instead of connecting to the zookeeper instance.
The reason I suspect zookeeper is the following from the log output of the
other two agents:
12:54:17.293 AMINFOorg.apache.zookeeper.ClientCnxn

configuration)
