[jira] [Created] (HADOOP-16644) Intermittent failure of
ITestS3ATerasortOnS3A: timestamp differences
Steve Loughran created HADOOP-16644:
---------------------------------------
Summary: Intermittent failure of ITestS3ATerasortOnS3A: timestamp differences
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
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}
