Primary shard is not active or isn't assigned is a known node ?

Question

I am running an elastic search version 4.1 on windows 8. I tried to index a document through java. When running a JUNIT test the error appears as below.

org.el

In my case the culprit was port 9300. It was blocked.

Elasticsearch will bind to a single port for both HTTP and the node/transport APIs.

It'll try the lowest available port first, and if it is already taken, try the next. If you run a single node on your machine, it'll only bind to 9200 and 9300.

So I unblocked port 9300 and I was good to go.

In REDHAT linux to unblock a port.

sudo firewall-cmd --zone=public --add-port=9300/tcp --permanent
sudo firewall-cmd --reload
sudo iptables-save | grep 9300
