Fabian Hueske created FLINK-3857: ------------------------------------ Summary: Add reconnect attempt to Elasticsearch host Key: FLINK-3857 URL: https://issues.apache.org/jira/browse/FLINK-3857 Project: Flink Issue Type: Improvement Components: Streaming Connectors Affects Versions: 1.0.2, 1.1.0 Reporter: Fabian Hueske
Currently, the connection to the Elasticsearch host is opened in {{ElasticsearchSink.open()}}. In case the connection is lost (maybe due to a changed DNS entry), the sink fails. I propose to catch the Exception for lost connections in the {{invoke()}} method and try to re-open the connection for a configurable number of times with a certain delay. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
