Subject [jira] [Commented] (HADOOP-14247) FileContextMainOperationsBaseTest should clean up test root path
Date Wed, 29 Mar 2017 09:44:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-14247?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15946829#comment-15946829
] 

Steve Loughran commented on HADOOP-14247:
-----------------------------------------

I'd like the assert check pulled from teardown. Otherwise the sequence of: test failure, teardown
failure, will only show the teardown exception, not the underlying test failure. I'd end up
having to edit the code, comment out the assert and rerun. Catch and log, fine: but teardowns
mustn't raise exceptions

> {{fileContextTestHelper}} will create random test root directory for each test case,
say $RANDOM. After test, we only delete the $RANDOM/test directory in tearDown(). This will
leave dangling directories under the {{test-dir}} directory. For S3A with S3Guard enabled,
those useless test directories will stay in DynamoDB forever. Let's clear out the test root
path, which is (generated randomly and) safe to remove.
