Daryn Sharp commented on HADOOP-14333:
--------------------------------------
Quiet bothered by hive using private hdfs apis with the added touch of
reflection. It's one thing to hack your own project because when you break it
you fix it, but completely different to hack another project... There should
be a followup jira to remove the method to ensure hive makes the change.
+1 After adding @Deprecated to the method and moving this jira to the hdfs
project.
> New exception thrown by (private) DFSClient API isHDFSEncryptionEnabled broke

> 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
> return !conf.getTrimmed(DFSConfigKeys.DFS_ENCRYPTION_KEY_PROVIDER_URI,
> "").isEmpty();
> }
> return client.isHDFSEncryptionEnabled();
> }
> {code}
