[GitHub] [spark] jiangxb1987 opened a new pull request #24595:
[SPARK-20774][CORE] Cancel the running broadcast execution on
BroadcastTimeout
jiangxb1987 opened a new pull request #24595: [SPARK-20774][CORE] Cancel the running broadcast execution on BroadcastTimeout
URL: https://github.com/apache/spark/pull/24595
## What changes were proposed in this pull request?
In the existing code, a broadcast execution timeout for the Future only causes a query failure, but the job running with the broadcast and the computation in the Future are not canceled. This wastes resources and slows down the other jobs. This PR tries to cancel both the running job and the running hashed relation construction thread.
## How was this patch tested?
Add new test suite `BroadcastExchangeExec`
