Rename directory in hdfs
I think you are missing the point about mv command(linux/hdfs).
When the destination already exists, if it's a file, an error message mv: 'dest': File exists.
In case of directory, the source will go inside it. So the command is working acceptably, just try it with a non-existent dest.
Now to resolve this, you can make use of hadoop's test command along with short circuit OR of linux.
hadoop fs -test -e dest || hadoop fs -mv src dest If the directory doesn't exist, invoke mv. You can even go further with the following:
hadoop fs -rmr dest hadoop fs -mv src dest This one deletes the dest dir first, then performs the move action. if this is not your intention, use the previous solution.
