I tried to start ES using command **sudo -i service elasticsearch start**

_Got an error_

# sudo -i service elasticsearch start

Starting elasticsearch: warning: Falling back to java on path. This behavior is deprecated. Specify JAVA\_HOME

I am using Amazon Linux, Java 1.8, EC 6.x

Anyone can help me?

How many RAM does your server have available? How much heap did you allocate for Elasticsearch in jvm.options?

With which option did you use the `free` command?

Also what about my question on the heap allocated in `/etc/elasticsearch/jvm.options`?

Hi EldrosKandar

Thanks for your replay, I apologized for the late replay now It's solved, I just upgrade Instance memory and now its work fine.

The latest version of Elastic Search not supported AWS t2.micro.

If you want a cheap and quick solution, you can have a look at [cloud.elastic.co](http://cloud.elastic.co). It starts at $17 per month IIRC.
