sometimes this mismatch can occur when you do a getFilestatus check on a newly
PUT file and the clock is off...I thought I'd fixed that, but maybe it can
still surface in overloaded test runs
> intermittent failure of ITestCommitOperations: too many s3guard writes

> Key: HADOOP-16622
> URL: https://issues.apache.org/jira/browse/HADOOP-16622
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.3.0
> Reporter: Steve Loughran
> Priority: Minor
>
> intermittent failure of ITestCommitOperations; expected 2 s3guard writes, saw
> 7
> the logged commit state shows that only two entries were added, so I'm not
> sure what is up. Proposed: in HADOOP-16207 I will add s3guard.operations log
> to debug so we get a trace of all DDB put/delete calls; this will let us
> debug it when it surfaces again
