> Though Hive should be fixed not to access DFSClient which is private to HADOOP, removing the throws added by HADOOP-14104 is a quicker solution to unblock hive.
> Hive code
> {code}
> private boolean isEncryptionEnabled(DFSClient client, Configuration conf) {
>   try {
>     DFSClient.class.getMethod("isHDFSEncryptionEnabled");
>   } catch (NoSuchMethodException e) {
>     // the method is available since Hadoop-2.7.1
>     // if we run with an older Hadoop, check this ourselves
