Vu Tan created SPARK-39082:
------------------------------
Summary: Fix FsHistoryProvider race condition between update and clean app data
Key: SPARK-39082
URL: https://issues.apache.org/jira/browse/SPARK-39082
Project: Spark
Issue Type: Bug
Components: Web UI
Affects Versions: 3.1.2, 3.2.1, 3.3.0
Reporter: Vu Tan
Assignee: XiDuo You
Fix For: 3.2.1, 3.3.0
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
java.util.NoSuchElementException: 1^@__main__^@+hdfs://xxx/application_xxx.inprogress
