Hi Lionel, We are not using Docker Image, hence we want to set it up manually. Could you provide us the “CREATE” statement for griffin indices along with “mappings”.

And when the spark application post metrics to ES directly, it succeed. ES will generate the indices by the first value you post to it.

Thank you for all your valuable help. We created an index for Griffin but we were not sure about what mappings we should use. Until we created this, we never got this index auto-created in ES….. And now that we have created the index, there are errors which are suggestive of missing “mappings” Is there an auto index create property that we need to enable somewhere in ES? I could not find anything in the config yml file though….

(or) Griffin services writes into it? [Answer] The metrics are persisted directly from spark application. Our URL is like this: http://localhost:9200/griffin/accuracy (if it is from Griffin service, it will work…. But from Spark executors, it wont work as localhost resolves to executor host) [Answer] I think you can modify "localhost" to the ip address of ES. But we have not created any index in “ES” called “griffin” or “accuracy”….? What should we be doing here? [Answer] You don't need to create the indices in ES, ES will create it when post metrics to it. For the "email" and "sms" parameters, they are not enabled in this version, you can just ignore them in env.json. BTW, has the metrics been persisted on HDFS?

One more: Yesterday we found that “email” and “sms” parts of the env.json are not configured properly. They appear as “array” in JSON… but the “EmailParam” and “SmsParam” do not expect a List… This was causing Spark jobs not to launch. We edited the env.json accordingly…. We hope we did the right thing… Can you confirm this?

What persist types did you configure in env.json? "log", "hdfs", "http"? - "log": print the metrics in application log. - "hdfs": the metrics will be persisted in hdfs path you've set. - "http": post the metrics to the "api" you've set, which should be the elasticsearch endpoint by default. You can choose multiple of them. If "http" is not configured correctly, post metrics to ES fails. If "hdfs" is configured, but you can not get any metric persisted in the "path", maybe griffin has not finish the calculation correctly. If "log" is configured, you can get the application log from yarn: yarn logs -applicationId <appId> > applog Then read the applog, find if there's any output metric calculated. If there's no metric persisted by any type of your persist configuration, you need to read the applog, and find the error message. Then you can show it to me, I'll help you find it.
