Duo Zhang commented on HBASE-20244:
-----------------------------------
For H2 we have the same problem, not only for H3, as we use internal APIs of
HDFS. We do not fix this issue is because that H3 is still not production ready.

> The private method was moved by HDFS-12574 to HdfsKMSUtil with different
> signature.
> To accommodate the above method movement, it seems we need to call the
> following method of DFSClient :
> {code}
> public KeyProvider getKeyProvider() throws IOException {
> {code}
> Since the new decryptEncryptedDataEncryptionKey method has this signature:
> {code}
> static KeyVersion decryptEncryptedDataEncryptionKey(FileEncryptionInfo
> feInfo, KeyProvider keyProvider) throws IOException {
