Description

At Spark 2.4.0/2.3.2/2.2.3, SPARK-24948 delegated access permission checks to the file system, and maintains a blacklist for all event log files failed once at reading. The blacklisted log files are released back after CLEAN_INTERVAL_S .

However, the files whose size don't changes are ignored forever because shouldReloadLog return false always when the size is the same with the value in KVStore. This is recovered only via SHS restart.
