Lefty Leverenz commented on HIVE-12598:
---------------------------------------

Doc note:  This adds configuration parameters 
*hive.llap.cache.allow.synthetic.fileid* and *hive.llap.io.use.fileid.path* to 
HiveConf.java, so they need to be documented in the wiki for release 2.0.0, in 
a new section for LLAP (along with the parameters listed for HIVE-11908).

> There is a TODO somewhere in code. We might get a synthetic fileId in absence 
> of the real one in some cases when another FS masquerades as HDFS, we should 
> be able to turn off fileID support explicitly for such cases as they are not 
> bulletproof.
