Shixiong Zhu created SPARK-11999:
------------------------------------
Summary: ThreadUtils.newDaemonCachedThreadPool(prefix,
maxThreadNumber) has unexpected behavior
Key: SPARK-11999
URL: https://issues.apache.org/jira/browse/SPARK-11999
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.5.2, 1.4.1, 1.6.0
Reporter: Shixiong Zhu
Currently, ThreadUtils.newDaemonCachedThreadPool(prefix, maxThreadNumber) will
throw RejectedExecutionException, if there are already `maxThreadNumber` busy
threads and we submit a new task. It's because `SynchronousQueue` cannot cache
any task.
