Lukas Majercak commented on HDFS-13714:
---------------------------------------
The rename used is standard Java. From docs:
{code:java}
Renames the file denoted by this abstract pathname.
*
* <p> Many aspects of the behavior of this method are inherently
* platform-dependent: The rename operation might not be able to move a
* file from one filesystem to another, it might not be atomic, and it
* might not succeed if a file with the destination abstract pathname
* already exists. The return value should always be checked to make sure
* that the rename operation was successful.{code}
Seems like this fails on Windows. Proposing to change to delete() followed by
renameTo()
