You must set ES_CLASSPATH var

[Siraris]

Everything with the cookbook seems to have run fine, except when I try to run ES it says "You must set the ES_CLASSPATH var". I see that this is defined in both /usr/local/elasticsearch/bin/elasticsearch.in.sh AND /usr/local/etc/elasticsearch/elasticsearch.en.sh but I don't know where it's looking for this variable in terms of actually starting ES. Any help would be much appreciated.

I should addendum that I followed Karel's instructions on from ES.org, but I got it working using Chef Server, instead of Chef solo. I don't know if there is anything that I did that could have effected the process, but from what I can tell, everything is installed properly (monit, nginx, etc), all the files look correct, the data directories look ok as well, so I'm a bit befuddled.

I all depends on how you run Elasticsearch. You can't just run elasticsearch -f, since no ES_CLASSPATH is set in that case. You have to use the provided init script or pass the path to the environment file:

ES_INCLUDE=/usr/local/etc/elasticsearch/elasticsearch-env.sh elasticsearch -f

So I added elasticsearch -f to the init script, and then ran sudo ./elasticsearch start. I got the following output, and I assume the last line is not good... :(:

[karmi]

So I added elasticsearch -f to the init script, and then ran sudo ./elasticsearch start.

I'm a bit confused by that :) The cookbook comes with an init script (service), and you can use the servicewrapper as well. I'm wondering about what kind of script you use to run elasticsearch.

I got the following output, and I assume the last line is not good... :(

1) ...[No automatic endpoint could be derived from region [us-west-2a]]

Indeed -- it means the discovery can't find an endpoint based on the us-west-2a value. I'm wondering about the configuration you use for AWS -- notice that you can set either a region (cloud.aws.region), which would be something like us-west-2 or the endpoint directly (cloud.aws.ec2.endpoint), which would be something like ec2.us-west-2.amazonaws.com in your case.
