Description

The caller of JavaKeyStoreProvider#renameOrFail assumes that it throws FileNotFoundException if the src does not exist. However, JavaKeyStoreProvider#renameOrFail calls the old rename API. In DistributedFileSystem, the old API returns false if the src does not exist.

That way JavaKeyStoreProvider fails to create a new key if the keystore is HDFS.
