Subject [jira] [Commented] (HADOOP-11244) The HCFS contract test testRenameFileBeingAppended doesn't do a rename
Date Thu, 30 Oct 2014 20:47:35 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11244?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14190805#comment-14190805

Noah Watkins commented on HADOOP-11244:
---------------------------------------

I read "no guarantees on concurrent operations" to refer to the thread safety of an implementation
of the file system object, but the scenario in this test can occur for a single thread. Is
that the intended meanin gof the spec?

> The test AbstractContractAppendTest::testRenameFileBeingAppended appears to assert the
behavior of renaming a file opened for writing. However, the assertion "assertPathExists("renamed
destination file does not exist", renamed);" fails because it appears that the file "renamed"
is never created (ostensibly it should be the "target" file that has been renamed).
