[BEAM-22] Clear Empty TransformExecutorServices Be sure to do all of the following to help us incorporate your contribution quickly and easily: - [x] Make sure the PR title is formatted like: `[BEAM-<Jira issue #>] Description of pull request` - [x] Make sure tests pass via `mvn clean verify`. (Even better, enable Travis-CI on your fork and ensure the whole test matrix passes). - [x] Replace "<Jira issue #>" in the title with the actual Jira issue number, if there is one. - [x] If this contribution is large, please file an Apache [Individual Contributor License Agreement](https://www.apache.org/licenses/icla.txt). --- This reduces the amount of objects tracked by the ExecutorServiceParallelExecutor when keys stop appearing. If this is not done, as new keys show up and no more work appears for old keys, the number of TransformExecutorServices grows, and we maintain a reference for all of them.
