[jira] [Updated] (SPARK-33790) Reduce the rpc call of getFileStatus
in SingleFileEventLogFileReader
[ https://issues.apache.org/jira/browse/SPARK-33790?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
dzcxzl updated SPARK-33790:
---------------------------
Description:
FsHistoryProvider#checkForLogs already has FileStatus when constructing SingleFileEventLogFileReader, and there is no need to get the FileStatus again when SingleFileEventLogFileReader#fileSizeForLastIndex.
This can reduce a lot of rpc calls and improve the speed of the history server.
