> Key: FLINK-24375
> URL: https://issues.apache.org/jira/browse/FLINK-24375
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Network
> Affects Versions: 1.14.0
> Reporter: Lijie Wang
> Assignee: Lijie Wang
> Priority: Major
> Fix For: 1.15.0
>
>
> Currently, the name of flush thread in RecordWriter does not contain subtask
> index, resulting in multiple threads with the same name on a single TM, which
> will confuse users.
> I think the "TaskInfo.getTaskNameWithSubtasks" should be used instead of
> "TaskInfo.getTaskName" in "StreamTask/BatchTask".
