[jira] Created: (HADOOP-2097) DistributedFileSystem.listPaths with
some paths causes directory to be cleared
DistributedFileSystem.listPaths with some paths causes directory to be cleared
------------------------------------------------------------------------------
Key: HADOOP-2097
URL: https://issues.apache.org/jira/browse/HADOOP-2097
Project: Hadoop
Issue Type: Bug
Components: dfs
Affects Versions: 0.14.2
Environment: Linux
Reporter: Bryan Duxbury
I am currently writing a Ruby wrapper to the Java DFS client libraries via JNI. While attempting to test the listPaths method of the FileSystem class, I discovered that passing a Path URI like "hdfs://tf11:7276/user/rapleaf" results in the /user/rapleaf directory being cleared of all contents. A path URI like "hdfs://tf11:7276/user/rapleaf/*" will list the contents of the directory without damage.
I have verified this by creating directories and listing via the bin/hadoop dfs -ls command.
Obviously passing an incorrectly formatted string a method that should be read-only should not have destructive effects. Also, the actual required path syntax for listings should be recorded in the documentation.

Chris Douglas commented on HADOOP-2097:
---------------------------------------
1) listPaths is deprecated; consider listStatus
2) I'm having trouble reproducing this. Can you provide some code or more explicit instructions?
