             Summary: direct-metrics-counter-committer threads might be leaking
                 Key: BEAM-3119
                 URL: https://issues.apache.org/jira/browse/BEAM-3119
             Project: Beam
          Issue Type: Bug
          Components: runner-direct
            Reporter: Etienne Chauchot
            Assignee: Thomas Groh


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.
{code}
com.carrotsearch.randomizedtesting.ThreadLeakError: There are still zombie threads that couldn't be terminated:
   1) Thread[id=296, name=direct-metrics-counter-committer, state=TIMED_WAITING, group=TGRP-ElasticsearchIOTest]
        at sun.misc.Unsafe.park(Native Method)

        at java.lang.Thread.run(Thread.java:745)

	at __randomizedtesting.SeedInfo.seed([59E504CA1B0DD6A8]:0){code}

I tried to increase the timeout to 30s (by patching randomizedtesting-runner-2.5.0.jar) but still gets a zombie thread.

To reproduce, just comment 
{code}
@ThreadLeakScope(ThreadLeakScope.Scope.NONE)
{code}
 in 
{code}
beam/sdks/java/io/elasticsearch-tests/elasticsearch-tests-5/src/test/java/org/apache/beam/sdk/io/elasticsearch/ElasticsearchIOTest.java
{code}
and run 
{code}
testRead()
{code}
