Hello Everyone,  
I get following warning when I start elasticsearch.

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

log4j:WARN No appenders could be found for logger (common.jna).  
log4j:WARN Please initialize the log4j system properly.  
log4j:WARN See [http://logging.apache.org/log4j/1.2/faq.html#noconfig](http://logging.apache.org/log4j/1.2/faq.html#noconfig) for

and "elasticsearch" doesn't start.

$ cat /etc/elasticsearch/elasticsearch.yml

Found the answer  
here. [http://elasticsearch-users.115913.n3.nabble.com/Problem-with-Des-config-and-logging-yml-td3198254.html](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
