Goodmorning everyone. I am trying to Flink connector Elasticsearch 5.2.1 and I have problems with the authentication XPACK
Using a different transport clients is currently (March 2017, Flink 1.2) not supported in Flink.
However, I've filed a JIRA to add the feature: FLINK-6065 Make TransportClient for ES5 pluggable
Until this has been implemented into Flink, I recommend overriding the ElasticsearchSink
and using a different call bridge calling the PreBuiltXPackTransportClient
.
