Subject [jira] [Commented] (HDFS-12981) HDFS renameSnapshot to Itself for Non Existent snapshot should throw error
Date Fri, 04 May 2018 17:52:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-12981?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16464197#comment-16464197

Xiao Chen commented on HDFS-12981:

Thanks [~saileshpatel] for creating the jira with good details, and [~knanasi] for working
on this!

The patch looks pretty good to me. Could you please fix the last checkstyles reported by jenkins?
We don't change existing stuff unnecessarily, but try not to introduce new ones.

There is also a unnecessary space change after {{TestSnapshotRename#testRenameToExistingSnapshot}},
let's drop that too.

> When trying to rename a non-existent HDFS  snapshot to ITSELF, there are no errors and
exits with a success code.
> The steps to reproduce this issue is:
> hdfs dfs -mkdir /tmp/dir1
> hdfs dfsadmin -allowSnapshot /tmp/dir1
> hdfs dfs 	-createSnapshot /tmp/dir1  snap1_dir
> Rename from non-existent to another_non-existent : errors and return code 1.  This is
>   hdfs dfs -renameSnapshot /tmp/dir1 nonexist another_nonexist  : 
>   echo $?
>   renameSnapshot: The snapshot nonexist does not exist for directory /tmp/dir1
> Rename from non-existent to non-existent : no errors and return code 0  instead of Error
and return code 1.
>   hdfs dfs -renameSnapshot /tmp/dir1 nonexist nonexist  ;  echo $?
> Current behavior:   No error and return code 0.
> Expected behavior:  An error returned and return code 1.
