             Summary: MongoDB plugin - Drill not showing correct error when 
using the wrong MongoDB database
                 Key: DRILL-1685
                 URL: https://issues.apache.org/jira/browse/DRILL-1685
             Project: Apache Drill
          Issue Type: Bug
          Components: Storage - MongoDB
    Affects Versions: 0.6.0
         Environment: Drill 0.6, MongoDB 2.6.5
            Reporter: Andries Engelbrecht


When connecting to MongoDB with multiple databases and collections drill fails 
to recognize the use of unavailable tables/collections.

Example: 
In the reviews database there are review, user, business collections/tables.
In the twitter database there is a tweets collection/table.

When connecting to the reviews database (use mongo.reviews;) and then 
incorrectly trying to access the tweets table in the twitter database sqlline 
returns the following error:

Query failed: Failure while setting up Foreman. Internal error: Error while 
applying rule DrillPushProjIntoScan, args 
[rel#5522:ProjectRel.NONE.ANY([]).[](child=rel#5521:Subset#0.ENUMERABLE.ANY([]).[],date=SUBSTRING($1,
 1, 10)), rel#5510:EnumerableTableAccessRel.ENUMERABLE.ANY([]).[](table=[mongo, 
reviews, tweets])] [68adba1a-3f55-4f95-ad61-be3a7550a26d]

Instead of simply identifying that the tweets table/collection is not in the 
current database.
