> Key: FLINK-18035
> URL: https://issues.apache.org/jira/browse/FLINK-18035
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.11.0
> Reporter: Yang Wang
> Priority: Blocker
> Fix For: 1.11.0
>
>
> In FLINK-17558, we introduce {{Executors#newCachedThreadPool}} to create
> dedicated thread pool for TaskManager io. However, it could not work as
> expected.
> The root cause is about the following constructor of {{ThreadPoolExecutor}}.
> Only when the workQueue is full, new thread will be started then. So if we
> set a {{LinkedBlockingQueue}} with {{Integer.MAX_VALUE}} capacity, only one
> thread will be started.
