[jira] [Created] (HBASE-24674) Procedure Executor doesn't handle burst well

Clara Xiong created HBASE-24674:
-----------------------------------

             Summary: 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


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.
