URL: https://github.com/apache/hadoop/pull/5452

   … in renameOrFail
   
   ### Description of PR
   
   Attempting to create a key a KMS is configured with the JavaKeystoreProvider 
and an HDFS store.  The calls to:
   ```
   renameOrFail(Path src, Path dest) throws IOException 
   ```
   
   ... fails with an IOException when it attempts to rename a file.  The 
calling code catches FileNotFoundException since the src file may not exist.
   
   Example:
   ```
   $ hadoop key create sample
   java.io.IOException: Rename unsuccessful : 
'hdfs://mycluster/security/kms.jks_NEW' to 
'hdfs://mycluster/security/kms.jks_NEW_ORPHANED_1662946593691'
    ```
   
   Update the implementation to check for the file, throwing a 
FileNotFoundException.
   
   ### How was this patch tested?
   
   Running in an Hadoop development environment docker image.
