xuanyuanking opened a new pull request #27418: [SPARK-30594][CORE] Do not post SparkListenerBlockUpdated when updateBlockInfo returns false URL: https://github.com/apache/spark/pull/27418 All credit to @Ngone51, Closes #27306. ### What changes were proposed in this pull request? If `updateBlockInfo` returns false, which means the `BlockManager` will re-register and report all blocks later. So, we may report two times for the same block, which causes `AppStatusListener` to count used memory for two times, too. As a result, the used memory can exceed the total memory. So, this PR changes it to not post `SparkListenerBlockUpdated` when `updateBlockInfo` returns false. And, always clean up used memory whenever `AppStatusListener` receives `SparkListenerBlockManagerAdded`. ### Why are the changes needed? This PR tries to fix negative memory usage in UI (https://user-images.githubusercontent.com/3488126/72131225-95e37e00-33b6-11ea-8708-6e5ed328d1ca.png, see #27144 ). Though, I'm not very sure this is the root cause for #27144 since known information is limited here. ### Does this PR introduce any user-facing change? No. ### How was this patch tested? Add new UT.
