> When I run ElasticsearchIOTests using ESv5, there is a thread leak control 
> mechanism ({{com.carrotsearch.randomizedtesting.ThreadLeakControl}}). It 
> waits for 5s for non-terminated threads at the end of a test. It detects 
> leaked {{direct-metrics-counter-committer}} thread.

> com.carrotsearch.randomizedtesting.ThreadLeakError: There are still zombie 
> threads that couldn't be terminated:
