----------------------------------
Summary: Spark 3.0 History Server May Never Finish One Round Log
Dir Scan
Key: SPARK-32529
URL: https://issues.apache.org/jira/browse/SPARK-32529
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 3.0.0
Reporter: Yan Xiaole
If there are a large number (>100k) of applications log dir, listing the log
dir will take a few seconds. After getting the path list some applications
might have finished already, and the filename will change from "foo.inprogress"
to "foo".
It leads to a problem when adding an entry to the listing, querying file status
like `fileSizeForLastIndex` will throw out a `FileNotFoundException` exception
if the application was finished. And the exception will abort current loop, in
a busy cluster, it will make history server couldn't list and load any
application log.
