[jira] [Updated] (HADOOP-14151) Swift treats empty file as
directory
[ https://issues.apache.org/jira/browse/HADOOP-14151?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
John Zhuge updated HADOOP-14151:
--------------------------------
Summary: Swift treats empty file as directory (was: Swift treats 0-len file as directory)
> Swift treats empty file as directory
> ------------------------------------
>
> Key: HADOOP-14151
> URL: https://issues.apache.org/jira/browse/HADOOP-14151
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs/swift
> Affects Versions: 3.0.0-alpha3
> Reporter: John Zhuge
>
> Unit test {{TestSwiftContractRootDir#testRmNonEmptyRootDirNonRecursive}} fails at {{assertIsFile(file)}}. This leads me to suspect swift treats 0-len file as directory. Confirmed by the following experiment:
> {noformat}
> $ ls -l /tmp/zero /tmp/abc
> -rw-rw-r-- 1 jzhuge wheel 4 Mar 7 13:19 /tmp/abc
> -rw-rw-r-- 1 jzhuge wheel 0 Mar 7 13:19 /tmp/zero
> $ bin/hadoop fs -put /tmp/zero /tmp/abc swift://jzswift.rackspace/
> 2017-03-07 13:24:09,321 INFO snative.SwiftNativeFileSystemStore: mv jzswift/zero._COPYING_ swift://jzswift.rackspace/zero
> $ bin/hadoop fs -touchz swift://jzswift.rackspace/touchz
> $ bin/hadoop fs -ls swift://jzswift.rackspace/
> Found 3 items
> -rw-rw-rw- 1 4 2017-03-07 13:36 swift://jzswift.rackspace/abc
