[jira] [Updated] (HADOOP-16644) Retrive modtime of PUT file from
store, via response or HEAD
[ https://issues.apache.org/jira/browse/HADOOP-16644?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Steve Loughran updated HADOOP-16644:
------------------------------------
Summary: Retrive modtime of PUT file from store, via response or HEAD (was: Intermittent failure of ITestS3ATerasortOnS3A: timestamp differences)
> Retrive modtime of PUT file from store, via response or HEAD
> ------------------------------------------------------------
>
> Key: HADOOP-16644
> URL: https://issues.apache.org/jira/browse/HADOOP-16644
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3, test
> Affects Versions: 3.3.0
> Environment: -Dparallel-tests -DtestsThreadCount=8 -Dfailsafe.runOrder=balanced -Ds3guard -Ddynamo -Dscale
> h2. Hypothesis:
> the timestamp of the source file is being picked up from S3Guard, but when the NM does a getFileStatus call, a HEAD check is made -and this (due to the overloaded test system) is out of sync with the listing. S3Guard is updated, the corrected date returned and the localisation fails.
> Reporter: Steve Loughran
> Priority: Major
>
> Terasort of directory committer failing in resource localisaton -the partitions.lst file has a different TS from that expected
> Happens under loaded integration tests (threads = 8; not standalone); non-auth s3guard
> {code}
