[jira] [Commented] (HADOOP-14548) S3Guard: issues running parallel
tests w/ S3N
[ https://issues.apache.org/jira/browse/HADOOP-14548?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16055026#comment-16055026 ]
Aaron Fabbri commented on HADOOP-14548:
---------------------------------------
My failures from `mvn verify -Dparallel-tests -Ds3guard -Ddynamo` in hadoop-tools/hadoop-aws:
{noformat}
Failed tests:
(1) ITestS3NContractRootDir>AbstractContractRootDirectoryTest.testListEmptyRootDirectory:188->Assert.assertEquals:555->Assert.assertEquals:118->Assert.failNotEquals:743->Assert.fail:88 listStatus on empty root-directory returned a non-empty list expected:<0> but was:<1>
(2) ITestJets3tNativeS3FileSystemContract>NativeS3FileSystemContractBaseTest.testListStatusForRoot:71 Root directory is not empty; expected:<0> but was:<1>
(3) ITestJets3tNativeS3FileSystemContract>FileSystemContractBaseTest.testListStatus:321 expected:<1> but was:<12>
Tests in error:
(4) ITestS3AContractRootDir>AbstractContractRootDirectoryTest.testRmEmptyRootDirNonRecursive:116 » PathIO
(5) ITestS3AEncryptionSSEC.testCreateFileThenMoveWithDifferentSSECKey:136->lambda$testCreateFileThenMoveWithDifferentSSECKey$14:147
(6) ITestJets3tNativeS3FileSystemContract>FileSystemContractBaseTest.testLSRootDir:847->FileSystemContractBaseTest.assertListFilesFinds:865 » FileNotFound
{noformat}
#4 Happens because root was not empty. Wondering if S3N folder objects caused the isEmptyDirectory() to be false?
[~mackrorysd] any thoughts on #5?
> 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
>
> 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.
