> Thread pools should release unused resources

> Key: HBASE-25547
> URL: https://issues.apache.org/jira/browse/HBASE-25547
> Project: HBase
> Issue Type: Improvement
> Components: master, regionserver
> Affects Versions: 3.0.0-alpha-1, 1.7.0, 2.5.0
> Reporter: Bharath Vissapragada
> Assignee: Bharath Vissapragada
> Priority: Minor
> Fix For: 3.0.0-alpha-1
>
>
> On this [PR|https://github.com/apache/hbase/pull/2909] [~stack] rightly
> pointed out that the thread pool just spins up threads that remain idle for
> 99.999% of time. Java's
> [ThreadPoolExecutor|https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/concurrent/ThreadPoolExecutor.html]
> lets us tune some configurations like the following for releasing the unused
> resources
> * corePoolSize
> * keepAliveTimeMs
> * allowCoreThreadTimeOut
> Current code makes it difficult to pass along these configurations to the
> executor service. Refactor and fix the defaults for low-priority thread pools
> to release resources quicker.
