Steve Loughran commented on HADOOP-17451:
-----------------------------------------
came with HADOOP-17271 and the S3A statistics rework. That is meant to be
better with HADOOP-16133 fixed, but clearly there's been a regression. which
surfaces with multipart uploads.
proposed
* fix the regression
* large upload tests to include probes for IOStats and thread local upload
stats.
I think its time to cut out some of the ITestHuge test cases and just have some
unit tests for the buffer mechanisms plus one live test. Separate patch tho'
> intermittent failure of S3A huge file upload tests: count of bytes uploaded

> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.0
> Reporter: Steve Loughran
> Priority: Major
>
> Intermittent failure of ITestHuge* upload tests, when doing parallel test
> runs.
> The count of bytes uploaded through StorageStatistics isn't updated. Maybe
> the expected counter isn't updated, and somehow in a parallel run with
> recycled FS instances/set up directory structure this surfaces the way it
> doesn't in a single test run.
