Work Description: aromanenko-dev commented on issue #9640: [BEAM-8300]:
KinesisIO.write throws NPE because producer is null
URL: https://github.com/apache/beam/pull/9640#issuecomment-535574848
@jhalaria To fix failed test, I think you need to add `tearDown` method into
`KinesisWriterFn`, like:
```
@Teardown
public void teardown() {
producer = null;
}
```
