> Elasticsearch connector hangs for threads deadlocked
> -----------------------------------------------------
>
> Key: FLINK-18535
> URL: https://issues.apache.org/jira/browse/FLINK-18535
> Project: Flink
> Issue Type: Bug
> Components: Connectors / ElasticSearch
> Affects Versions: 1.10.0
> Reporter: DeFOX
> Priority: Major
> Labels: Connector, ElasticSearch, stale-major
>
> When using the connector created by
> org.apache.flink.streaming.connectors.elasticsearch7.ElasticsearchSink.Builder
> to sink data to ES(es7.7.1 and es6.8.5), flink job will finally hang for
> threads deadlocked after a while.
> And connector created by
> org.apache.flink.streaming.connectors.elasticsearch6.ElasticsearchSink.Builder
> will not result in this deadlocked situation.
> This deadlocked issue may come from this
> pr：[https://github.com/elastic/elasticsearch/pull/41451]
> So upgrade version of the dependencies of ES may fix this bug.
