> --------------------------------------------------------------------
>
> Key: FLINK-18702
> URL: https://issues.apache.org/jira/browse/FLINK-18702
> Project: Flink
> Issue Type: Bug
> Components: Connectors / ElasticSearch
> Affects Versions: 1.10.0, 1.10.1
> Reporter: Jun Qin
> Assignee: Jun Qin
> Priority: Major
>
> Flink elasticsearch connector leaking threads and classloaders thereof. This results in OOM Metaspace when ES sink fails and restarted many times.
> This issue is visible in Flink 1.10 but not in 1.11 because Flink 1.11 does not create new class loaders in case of recoveries (FLINK-16408)
>
> Reproduction:
> * Start a job with ES sink in a Flink 1.10 cluster, without starting the ES cluster.
