How to start OpenTSDB?

Question

I'm following the getting started instructions for OpenTSDB, but I get the below-shown errors when running the program. Can anyone help?

When running command:

./build/tsdb tsd --port=4242 --staticroot=build/staticroot --cachedir="$tsdtemp"

I get this error:

It seems like your zookeeper is down/not configured on poort 2181

you can start by checking the zoo.cfg file where you installed zookeepr
