---------------------------------
Summary: Fix FsHistoryProvider race condition between list and
delet log info
Key: SPARK-37659
URL: https://issues.apache.org/jira/browse/SPARK-37659
Project: Spark
Issue Type: Bug
Components: Web UI
Affects Versions: 3.1.2, 3.2.1, 3.3.0
Reporter: XiDuo You
After SPARK-29043, FsHistoryProvider will list the log info without waitting
all `mergeApplicationListing` task finished.
However the `LevelDBIterator` of list log info is not thread safe if some other
threads delete the related log info at same time.
There is the error msg:
{code:java}
21/12/15 14:12:02 ERROR FsHistoryProvider: Exception in checking for event log
updates
