      Description

      The mr1.js jstest tests this but doesn't check the command result and thus the test still passes:

          res = db.runCommand({mapreduce: "mr1", map: m2, reduce: r2, out: {inline: true}});
          print("t4: " + res.timeMillis);
      

      The massert is when it tries to drop its temp collections:

      [MongoDFixture:job0] 2016-12-08T09:28:13.441-0500 I -        [conn4] Assertion: 28539:need a valid database name src/mongo/db/concurrency/d_concurrency.cpp 106
      

      This massert does not occur in 3.2 or 3.4.
