Subject [jira] [Commented] (HADOOP-13734) ListStatus Returns Incorrect Result for Blank File
Date Wed, 19 Oct 2016 11:15:58 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15588461#comment-15588461

Kevin Huang commented on HADOOP-13734:
--------------------------------------

I have found where the bug happened in source code, see [code|https://github.com/apache/hadoop/blob/trunk/hadoop-tools/hadoop-openstack/src/main/java/org/apache/hadoop/fs/swift/snative/SwiftNativeFileSystemStore.java#L247].
 However, I have no idea about the fix so far.

>                 URL: https://issues.apache.org/jira/browse/HADOOP-13734
>             Project: Hadoop Common
>          Issue Type: Bug
>          Components: fs/swift
>            Reporter: Kevin Huang

> Reproduce steps:
> 1. Create a blank file on Swift via Swift client(e.g Cyberduck)
> 2. Use Hadoop Swift API to get file status. The following is the code example:
> {code}
>         Configuration hadoopConf = new Configuration();
>         hadoopConf.addResource("swift-site.xml"); // Set Swift configurations
>         FileSystem fs = FileSystem.get(new URI("swift://containername.myprovider/"),
hadoopConf);
>         FileStatus[] statuses = fs.listStatus(new Path("/mydir"));
>         for(FileStatus status : statuses) {
>             System.out.println(status);
>         }
> {code}
> Result:
> {code}
> SwiftFileStatus{ path=swift://bdd-edp.bddcs/mydir/blankfile; isDirectory=true; length=0;
blocksize=33554432; modification_time=1476875293230}
> {code}
> API treated blankfile as a directory. That is incorrect.
