--------------------------------------------------------------
To fix this problem, I think we no longer need to exclude `com.carrotsearch:
hppc` from the sql connector jar of elasticsearch-6. In addition, I tested the
6.3.1 version of es excluding `hppc`, and the 6.8.20 version of es including
`hppc`, all of which work well, hope this can help confirm which versions of
flink(since the es connector was previously maintained in apache/flink repo)
has this problem.
I am willing to fix this, [~chesnay] would you like to assign this ticket to me
and I will open a pull request later.

> When I use sql-client to submit job that sink data to elasticsearch, it seems
> that the `NoClassDefFoundError` arises as shown in the figure below. Note
> that the connector jar I used is
> flink-sql-connector-elasticsearch6-4.0-SNAPSHOT.jar, it is a uber jar
> compiled from flink-connector-elasticsearch repo's main branch.

> Through some investigations, I found that in
> flink-sql-connector-elasticsearch6 module's pom.xml, we manually excluded the
> `com.carrotsearch: hppc` dependency, which is no problem for the 6.3.1
> version of elasticsearch. However, FLINK-25189 bump this to 6.8.20, which
> does requires the dependence of hppc. Therefore, an `NoClassDefFoundError`
> occurred.
