---------------------------------
Summary: Executors#newCachedThreadPool could not work as expected
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
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.
