    • Joins with Mongo storage plugin

    Description

      As pointed in review board(https://reviews.apache.org/r/25996/), joins are not working with mongo storage plugin.

      Few sample queries:

      1) SELECT t1.first_name FROM mongo.employee.`empinfo` t1 JOIN  mongo.employee.`empinfo` t2 ON  t1.`employee_id` = t2.`employee_id`

2) SELECT t1.first_name, t2.last_name FROM mongo.employee.`empinfo`  t1  JOIN  cp.`employee.json` t2  ON t1.`employee_id` = t2.`employee_id` limit 10

      The Error is as below:
