The check if connection is lost or not & then retry for connection is a good suggestion. Made the change. separated the methods for connection creation & connection status check. > 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: 1.1.0, 1.0.2 > Reporter: Fabian Hueske > Assignee: Subhobrata Dey > > 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)
