Subject [jira] [Commented] (HADOOP-15940) ABFS: For HNS account, avoid unnecessary get call when doing Rename
Date Mon, 19 Nov 2018 18:18:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15940?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16692082#comment-16692082

Da Zhou commented on HADOOP-15940:
----------------------------------

Sorry I made a mistake in my previous comment, I highlighted the corrected one:
 1. rename a file to itself, should return true
 2. rename a dir to itself, should return *false*. (According to the [Contract test,|https://github.com/apache/hadoop/blob/a55d6bba71c81c1c4e9d8cd11f55c78f10a548b0/hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/fs/FileSystemContractBaseTest.java#L765]
this should return false)
 3. move file/dir to same parent folder, return true.
