I m trying to setup an elastic search cluster using a persistent Volume as storage in a kubernetes cluster.  
I have a NFS mount acting as a persistent volume.

I read in the documentation that elastic search uses elasticsearch.yml file and there is a path.data environment variable in that file which can be set to different values (in my case i want to set it to the NFS mount represented by the PV). I am not able to find this file in my system unless i start the deployment.

I m using a set of yaml files to deploy this cluster and create a master node, client node and 2 data nodes along with client service and a master service.

But i see that data is always stored at /usr/share/elasticsearch directory and not at the mount path specified by me in data.yml file.  
How do i specify the elasticsearch to use the NFS mount path to store data while deploying the cluster using kubectl commands

The following is my data yml file.

apiVersion: extensions/v1beta1

I see that the data is stored at /usr/share/elasticsearch/data and not in the NFS mount.  
How do i force the elastic search to do this ?

Do not use NFS as a data path for Elasticsearch. It is not supported and known to be problematic. Also, performance will be very bad.

That being said, if you which to use _another_ type of storage you need to mount a volume in `/use/share/elasticsearch/data` which is the data path used by the Docker image.
