I am working on a new Elastic stack cluster and I am unable to start Elastic. I am assuming it is a filesystem/permissions issue, but I cant pin it down. I have a 1TB Samba share that is mounted to /home/elastic/esstorage and in the elasticsearch.yml i have "path.data: /home/elastic/esstorage". there was a permissions issue, but i corrected it and cleared out the files that were created under the wrong credentials, but now I am running into this error when i try to start elastic ```auto [2018-11-05T09:41:39,477][INFO][o.e.n.Node] [Masternode-1] initializing ...

I'd open an issue as getting a NPE is never a good thing. However it's absolutely not recommended to use a network drive to store elasticsearch data. You should not do that IMHO. ---

Thank you, I Went over it with Management and we're moving away from the CIFS share. ---
