Region

[prepor]

Hello.

How to set region for EMR cluster?

[prepor]

For now i just monkeypatch lemur:

(defn emr-client [aws-creds]
  (doto (AmazonElasticMapReduceClient. aws-creds)
    (.setEndpoint "elasticmapreduce.eu-west-1.amazonaws.com")))

Is there better way? )

You can avoid the monkeypatch, using this trick in your jobdef:

(require '[com.climate.services.aws.emr :as emr]
'[com.climate.services.aws.common :as aws])

(import
com.amazonaws.services.elasticmapreduce.AmazonElasticMapReduceClient)

(defn eu-west-1-emr-client
[aws-creds](doto %28AmazonElasticMapReduceClient. aws-creds%29
%28.setEndpoint)))

...

(with-bindings {#'emr/emr (aws/aws eu-west-1-emr-client
(aws/aws-credential-discovery))}
(fire! test-cluster-fn test-step-fn))

See this discussion with more detail:
https://groups.google.com/forum/#!topic/lemur-user/eHyQrB6qMXM. Ideally
this would be easier, maybe a :region key in defcluster. A pull-request
would be happily accepted.
