Here is my storage-plugins.json:
{
storage:{
dfs: {
type: file,
connection: file:///
},
formats: {
psv : {
type: text,
extensions: [ tbl ],
delimiter: |
},
csv : {
type: text,
extensions: [ csv
It looks like you need to specify the data source you are using (appearing
in the storage section of your config file), I believe there is a way when
you are connecting to pass a default schema, but it currently isn't set up
to bring you right into a schema, even if you only have line specified in
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
