[jira] [Commented] (HDDS-4026) Dir rename failed when sets
'ozone.om.enable.filesystem.paths' to true
[ https://issues.apache.org/jira/browse/HDDS-4026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17164438#comment-17164438 ]
Rakesh Radhakrishnan commented on HDDS-4026:
--------------------------------------------
*Analysis:* With flag to true, it is not adding the trailing slash to the 'fromKeyName' and 'toKeyName', which results in KEY_NOT_FOUND from KeyTable.
{code:java}
String fromKeyName = keyArgs.getKeyName();
// value coming as '/vol2/bucket2/subdir2'. For a directory, it stored the key with trailing slash and it should be like '/vol2/bucket2/subdir2/'.
{code}
We can verify this case via unit test case - [testFileSystem#testRenameDir()|https://github.com/apache/hadoop-ozone/blob/master/hadoop-ozone/integration-test/src/test/java/org/apache/hadoop/fs/ozone/TestOzoneFileSystem.java#L193]. by setting flag to true.
