> Procedure Executor doesn't handle burst well
> --------------------------------------------
>
> Key: HBASE-24674
> URL: https://issues.apache.org/jira/browse/HBASE-24674
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 2.2.5
> Reporter: Clara Xiong
> Priority: Major
>
> Currently, Procedure Executor checks for stuck threads every 5 sec. If >50%
> are stuck, one worker thread is added until maxPoolSize is reached. In a
> burst scenario, this cannot catch up and causes thread starvation. A smarter
> algorithm can be used to measure the pressure and step up automatically.
