Do we expect to ever enable this test again? if not, let's just remove it.
> Elasticsearch 1.x ITCase still instable due to embedded node instability

> Key: FLINK-6867
> URL: https://issues.apache.org/jira/browse/FLINK-6867
> Project: Flink
> Issue Type: Bug
> Components: ElasticSearch Connector, Tests
> Reporter: Tzu-Li (Gordon) Tai
> Assignee: Tzu-Li (Gordon) Tai
>
> The integration tests for Elasticsearch 1.x seems to still be instable, being
> that the test is failing more frequently recently. One example is [1].
> The last attempt to fix this was FLINK-5772, in which the test attempts was
> increased to 3. This doesn't seem to fix the issue. In the worst scenario,
> since the root cause is an instability with Elasticsearch 1.x's embedded
> node, and ES 1.x is a very old version that is usually recommended to be
> upgraded from, we could also consider removing the IT test for ES 1.x.
