> Seeing some slowness for certain fs tests when run against S3. Since they in the hour range, I think its useful to track it down and distinguish between a test infrastructure issue vs. an impala/s3 issue.
> Here are logs from a recent run (note the time gaps in the log entries):

> There are several other tests that take in the 10 minute to minute range. Highlighting above the longest ones (> hour).
