Subject [jira] [Commented] (HADOOP-15627) Failure in ITestS3GuardWriteBack.testListStatusWriteBack
Date Mon, 23 Jul 2018 23:58:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15627?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16553587#comment-16553587
] 

Steve Loughran commented on HADOOP-15627:
-----------------------------------------

Cause here is that if the test FS has s3guard enabled always, then the{{Assume.assumeTrue(getFileSystem().hasMetadataStore());}}
check at the start of the test holds, but the FS creation code is only consistent if you set
the -Ds3guard on the test run. otherwise, metadata setup in maybeEnabledS3Guard is skipped,
and your test filesystems are all copies of the FS as created/configured by default. Which
does have s3guard enabled, and with whatever writeback/auth options that comes with. 

Fix: change how the new FS instances are configured and created
