FAQ
not to sound annoying but I got the same issue on a new node in my cluster.

It seems that using Flume with an HBase sink won't work unless Flume is
installed on an HBase region server. It seems that it's dependent on the
region server's zoo.cfg.

I don't know what to do in order to fix this. Perhaps giving Flume it's own
zoo.cfg file independent of HBase's classpath?

Anyhow, temporary fix is to install a Region Server role along with Flume
and it makes it work.

It seems that uninstalling zookeeper and re-installing it then gave me the
option to "Update Client Configurations" that seems to push out the zoo.cfg
to all the Flume hosts properly.

Once I did this, Flume finds my Hbase.

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:
