DeFOX created FLINK-18535:
-----------------------------
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.
