Subject Re: Local Cluster have problem with connect to elasticsearch

Hi Rafal,

>From your description, it seems like Flink is complaining because it cannot
access the Elasticsearch API related dependencies as well. You'd also have
to include the following into your Maven build, under <artifactItems>:


Now your built jar should correctly include all required dependencies (the
connector & Elasticsearch API).

As explained in  Linking with modules not contained in the binary

, it will be enough to package dependencies along with your code for Flink
to access all required dependencies, and you wouldn't need to copy the jar
to the lib folder. I would recommend to clean up the lib folder of the
previous jars you copied, and follow this approach in the future, just in
case they mess up the classloader.

As with your first attempt that Flink cannot find any Elasticsearch nodes
when executed in the IDE, I'm suspecting the reason is that the
elasticsearch2 connector by default uses version 2.2.1, lower than your
cluster version 2.3.2. I had previous experience when Elasticsearch
strangely complains not finding any nodes when using lower client versions
than the deployment. Can you try compiling the elasticsearch2 connector with
the option -Delasticsearch.version=2.3.2, and use the newly build connector
jar, following the same method mentioned above?

Hope this helps!
