I get following warning when I start elasticsearch.

$ elasticsearch -Des.config=/etc/elasticsearch/elasticsearch.yml -f

log4j:WARN Please initialize the log4j system properly.

and "elasticsearch" doesn't start.

Found the answer
here. http://elasticsearch-users.115913.n3.nabble.com/Problem-with-Des-config-and-logging-yml-td3198254.html
But is there a way to specify location of logging.yml file? and where does
elasticsearch look for logging.yml if not found in PWD?

Just adjusted "path.conf", in elasticsearch.yml and problem solved.

Thanks for posting the solution, mate! I just built and installed the Debian
package, and this problem bit me, too.

I had to specify the following settings in my elasticsearch.yml before ES
would start:

path.conf: /etc/elasticsearch
path.data: /var/lib/elasticsearch
path.work: /tmp/elasticsearch
path.logs: /var/log/elasticsearch
