> We need a separate audit log similar to HDFS audit log, where table/etc. 
> accesses can optionally be logged. It is especially important with SQL 
> standard auth, since the default model for that is doAs=false, and the lack 
> of impersonation makes HDFS audit logs relatively useless. There's some audit 
> logging in metastore, but it does into the main log and I don't think anyone 
> ensured it is sufficient and consistently applied even within the scope of 
> metastore; there's also a question of whether accesses at the task level can 
> be audited, and how (should HS2 audit-log each task x input combo, since 
> tasks cannot log to a permanent location?).
