> Currently, Spark HistoryServer use a HashMap named fileToAppInfo in class
> FsHistoryProvider to store the map of eventlog path and attemptInfo.
> When use ThreadPool to Replay the log files in the list and merge the list of
> old applications with new ones, multi thread may update fileToAppInfo at the
> same time, which may cause Thread-safety issues.
> {code:java}
> for (file <- logInfos) {
> tasks += replayExecutor.submit(new Runnable {
> override def run(): Unit = mergeApplicationListing(file)
> })
> }
> {code}
