I'm trying run bin/Elasticsearch and that is what i got. Elasticsearch.service is runing.
Can some1 help solve this problem?

Is this a stock Elasticsearch or did you change your configuration/setup, i.e. the logging configuration? If so, can you try to revert that change and see if it works?

Thanks for replaying. I solved my problem by rebooting debian server and reinstalling Elasticsearch.
