Elasticsearch, Permission Denied during configuration

Hi People!

Im new to both Linux & ELK stack. So this might be a simple matter.

During configuration of Elasticssearch-2.2.0 I type the command "./bin/elasticsearch" under an account i created (ELKuser) but i get back this:

log4j: ERROR setFile (null,true) call failed.
/home/elasticsearch-2.2.0/logs/elasticsearch.log (Permission denied)

Has anyone seen this before? If so what do you go about fixing this?

That's an odd path to extract ES to.
What user are you trying to run this as and does it have the correct permissions?
