Hi Piyush, You're right that we don't support ViewFileSystem at the moment. It looks like IMPALA-77 was resolved by failing more gracefully for viewfs.
I suspect it just needs some targeted code changes and testing - the logic for different filesystems is mostly the same with some tweaks. I'm not sure when this will happen - it will likely largely depend on when someone steps forward to do it. I believe pointing directly to the hdfs:// URLs should work. - Tim On Thu, Nov 30, 2017 at 11:39 AM, Piyush Narang <[email protected]> wrote: > Hi folks, > > > > Our company is looking to experiment with setting up Impala for some of > our adhoc query workloads.
