[jira] [Commented] (HIVE-16047) Shouldn't try to get KeyProvider unless encryption is enabled

["Andrew Wang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-16047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15977980#comment-15977980 ] 

Andrew Wang commented on HIVE-16047:
------------------------------------

Hi folks, DFSClient is a private API. After HADOOP-14333, it broke Hive compilation because we changed isHdfsEncryptionEnabled to throw an exception.

We'd be pleased to add public APIs at HDFS-11687 for whatever Hive needs wrt HDFS encryption (or even HDFS more broadly). I'd be nice to revert this for now (since it's a pretty minor fix) and revisit once HDFS-11687 is resolved. I already filed and linked HIVE-16490 to help track this work.
