> Project: Hadoop Common

> TestAggregatedLogFormat.testContainerLogsFileAccess test case fails on
> Windows. The test case try to simulate a situation where first log file is
> owned by different user (probably symlink) and second one by the user itself.
> In this situation, the attempt to try to aggregate the logs should fail with
> the error message "Owner ... for path ... did not match expected owner ...".
> The check on file owner happens at {{AggregatedLogFormat.write()}} method.
> The method calls {{SecureIOUtils.openForRead()}} to read the log files before
> writing out to the OutputStream.
> {{SecureIOUtils.openForRead()}} use {{NativeIO.Posix.getFstat()}} to get the
> file owner and group. We don't have {{NativeIO.Posix.getFstat()}}
> implementation on Windows; thus, the failure.
