Jungtaek Lim created STORM-1629:
-----------------------------------
Summary: Files/move doesn't work properly with non-empty directory
in Windows
Key: STORM-1629
URL: https://issues.apache.org/jira/browse/STORM-1629
Project: Apache Storm
Issue Type: Bug
Components: storm-core
Affects Versions: 1.0.0, 2.0.0
Environment: Windows
Reporter: Jungtaek Lim
Assignee: Jungtaek Lim
Priority: Blocker
Distributed version of download-storm-code uses Files#move().
It runs well on *Nix (including OSX) but fails on Windows.
Javadoc describes this behavior, please refer below link.
https://docs.oracle.com/javase/7/docs/api/java/nio/file/Files.html#move(java.nio.file.Path,%20java.nio.file.Path,%20java.nio.file.CopyOption...)
{quote}
When invoked to move a directory that is not empty then the directory is moved
if it does not require moving the entries in the directory. For example,
renaming a directory on the same FileStore will usually not require moving the
entries in the directory. When moving a directory requires that its entries be
moved then this method fails (by throwing an IOException). To move a file tree
may involve copying rather than moving directories and this can be done using
the copy method in conjunction with the Files.walkFileTree utility method.

If directory is not empty, file system should treat "move directory" as
"rename".
Unfortunately, file system on Windows 8 doesn't.
We should change the way to be compatible with both kinds of OS.
