> The test creates some log files and sets their modified time based on the
> starting time of the test; then it verifies that the right files were picked
> up when trying to stream log files from a 5 second window starting 10 seconds
> before the starting time of the test. However, for gz files, we use the time
> from their name instead of the modified file time, and assume they last for
> an hour; but, they don't store second or minute granularity.
> So, if the test is started within the first 4 seconds, for example at 8:00:03
> on 12/20/2012, then the gz file will be named {{oozie.log-2012-12-20-08.gz}}
> and the window we're looking to stream files from is between 7:59:53 and
> 7:59:58. The start and end times of the gz file would be considered to be
> 8:00:00 and 9:00:00 respectively, which doesn't overlap with the window (and
> the test expects the gz file to fall into the window). If the test is
> started after the first 4 seconds, for example at 8:07:00, then the gz file
> will be named {{oozie.log-2012-12-20-08.gz}} still, but the window would be
> 8:06:50 to 8:06:55, which overlaps with the gz file start and end times of
> 8:00:00 and 9:00:00 (so it works as expected).
> One solution is to change the test to use hours instead of seconds for its
> window.
