    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.
