Sorry, that was a bit of a roundabout way of describing the process. The normal connection should just give you a session where you can query all schemas (in your config file, dfs is the only schema listed). You simply need to write it as dfs.`filepath'
I was looking at the connection docs quickly and I couldn't find the exact option for specifying schema. I'll reply if I find something later today (its likely just schema or default_schema). Doing this would simply allow you to leave off the dfs part of the name, as it will assume your queries will want to default to that schema. -Jason On Fri, May 23, 2014 at 10:20 AM, 南在南方 <i02...@qq.com> wrote: > I found that there are two configuration files in drill home > (storage-engines.json and storage-plugins.json) .
