> Exception thrown by DFSClient API isHDFSEncryptionEnabled broke hacky hive code
> --------------------------------------------------------------------------------
>
> Key: HADOOP-14333
> URL: https://issues.apache.org/jira/browse/HADOOP-14333
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Yongjun Zhang
> Assignee: Yongjun Zhang
>
> 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}
