Wei-Chiu Chuang commented on HADOOP-17255:
------------------------------------------
I was always under the impression that key store isn't suppose to be in HDFS
because it won't work. Even if you change the rename() call, there are other
FileSystem calls invoked by JavaKeyStore that wouldn't work. Am I right?

> 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.
