------------------------------
Summary: ShortCircuitCache#close is not releasing
ScheduledThreadPoolExecutors
Key: HDFS-7922
URL: https://issues.apache.org/jira/browse/HDFS-7922
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Rakesh R
Assignee: Rakesh R
ShortCircuitCache has the following executors. It would be good to shutdown
these pools during ShortCircuitCache#close to avoid leaks.
{code}
/**
* The executor service that runs the cacheCleaner.
*/
private final ScheduledThreadPoolExecutor cleanerExecutor
= new ScheduledThreadPoolExecutor(1, new ThreadFactoryBuilder().
setDaemon(true).setNameFormat("ShortCircuitCache_Cleaner").
build());
/**
* The executor service that runs the cacheCleaner.
*/
private final ScheduledThreadPoolExecutor releaserExecutor
= new ScheduledThreadPoolExecutor(1, new ThreadFactoryBuilder().
setDaemon(true).setNameFormat("ShortCircuitCache_SlotReleaser").
build());
{code}
