Gopal Vijayaraghavan commented on HIVE-23212:
---------------------------------------------
A DFS client needs {{hadoop.security.key.provider.path}} - if that isn't
configured with a KMS, then the EZs won't be usable.
> SemanticAnalyzer::getStagingDirectoryPathname should check for encryption
> zone only when needed
> -----------------------------------------------------------------------------------------------

> When cluster does not have encryption zones configured, this ends up making 2
> calls to NN unnecessarily. It would be good to guard it with config or check
> for the KMS config from HDFS and invoke it on need basis.
