Description of the Change

Running the zookeeper installation via ansible and virtualbox vagrant I observed that sometimes the output of zookeeper with netcat is empty. This causes the package to be installed newly.

Instead adding -q 3 will wait 3 seconds before disconnecting from netcat side or disconnecting when server sends a disconnect. Which fixes the problem for me.

Benefits

Provisioning is more stable as connection is longer open and output from zookeeper is provided.

Possible Drawbacks

Worst case is the provisioning takes 3 seconds longer.

Applicable Issues

None known.
