Subject [jira] [Created] (HADOOP-10948) SwiftNativeFileSystem's directory is incompatible with Swift and Horizon
Date Fri, 08 Aug 2014 12:34:12 GMT
Kazuki OIKAWA created HADOOP-10948:
--------------------------------------

             Summary: SwiftNativeFileSystem's directory is incompatible with Swift and Horizon
                 Key: HADOOP-10948
                 URL: https://issues.apache.org/jira/browse/HADOOP-10948
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs/swift
    Affects Versions: 2.4.1, 3.0.0
            Reporter: Kazuki OIKAWA


SwiftNativeFileSystem's directory representation is zero-byte file.
But in Swift / Horizon, directory representation is a trailing-slash.

This incompatibility has the following issues.
* SwiftNativeFileSystem can't see pseudo-directory made by OpenStack Horizon
* Swift/Horizon can't see pseudo-directory made by SwiftNativeFileSystem. But Swift/Horizon
see a zero-byte file instead of that pseudo-directory.
* SwiftNativeFileSystem can't see a file if there is no intermediate pseudo-directory object.
* SwiftNativeFileSystem makes two objects when making a single directory
(e.g. "hadoop fs -mkdir swift://test.test/dir/" => "dir" and "dir/" created)
