-----------------------------

             Summary: 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


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.
