> Refactor AbstractRetryHandler in ConfigNode
> -------------------------------------------
>
> Key: IOTDB-4396
> URL: https://issues.apache.org/jira/browse/IOTDB-4396
> Project: Apache IoTDB
> Issue Type: Bug
> Reporter: Jinrui Zhang
> Assignee: Yongzao Dan
> Priority: Major
>
> Current implementation of AbstractRetryHandler is confusing.
>
> The aim of it is to simplify the implementation of RETRY when sending request
> to several datanodes. But it doesn't encapsulate the logic inside the
> abstract class but let the implementations to maintain the retry status,
> which is un-safe.
>
> Refactor target:
> # Encapsulate the `countDownLatch` inside the abstract class rather than
> make it as a constructor variable
> # Maintain the remove logic of DataNodeLocations insides the class
