Aaron Fabbri commented on HADOOP-14548:
---------------------------------------
For the record, here are the failures on trunk (no s3guard) if I try to run
s3a/s3n integration tests in parallel, using a single bucket
{noformat}
Failed tests:
(2)
ITestJets3tNativeS3FileSystemContract>NativeS3FileSystemContractBaseTest.testListStatusForRoot:73
Root directory is not empty; expected:<0> but was:<2>
(3)
ITestJets3tNativeS3FileSystemContract>FileSystemContractBaseTest.testListStatus:321
expected:<1> but was:<12>
Tests in error:
(4)
ITestS3AContractRootDir>AbstractContractRootDirectoryTest.testRmEmptyRootDirNonRecursive:116
» PathIO
(6)
ITestJets3tNativeS3FileSystemContract>FileSystemContractBaseTest.testLSRootDir:833->FileSystemContractBaseTest.assertListFilesFinds:851
» FileNotFound
{noformat}
If I point s3a/s3n contract tests at different buckets, I still get the first
three (but not #6).
> S3Guard: issues running parallel tests w/ S3N
> ----------------------------------------------

> Key: HADOOP-14548
> URL: https://issues.apache.org/jira/browse/HADOOP-14548
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Reporter: Aaron Fabbri
> Assignee: Aaron Fabbri
>
> In general, running S3Guard and parallel tests with S3A and S3N contract
> tests enabled is asking for trouble: S3Guard code assumes there are not
> other non-S3Guard clients modifying the bucket.
> Goal of this JIRA is to:
> - Discuss current failures running `mvn verify -Dparallel-tests -Ds3guard
> -Ddynamo` with S3A and S3N contract tests configured.
> - Identify any failures here that are worth looking into.
> - Document (or enforce) that people should not do this, or should expect
> failures if they do.
