Robert Metzger commented on FLINK-11720:
----------------------------------------
Maybe you saw it in the Flink 1.6.2 release thread before? (I think Fabian
mentioned it there)
Compiling against 5.3.0 fails with:
{code:java}
/home/robert/flink/flink-connectors/flink-connector-elasticsearch5/src/test/java/org/apache/flink/streaming/connectors/elasticsearch/EmbeddedElasticsearchNodeEnvironmentImpl.java:[27,39]
package org.elasticsearch.node.internal does not exist{code}
If that's the only thing we depend on, I'm sure there's a workaround.
