      Description

      Importing this the attached file `posts.json` through mongoimport 2.6 parses each line as individual documents while 3.2 parses the full file as one single document, that in this case causes the operation to fail.

      On 3.2

      mongoimport  -d blog -c posts --drop posts.json                                                                           [11:08:06]

      I've also added a slight change to the file by transforming it into a json array (attached file a.json) also get different behaviour:

      On 3.2

      mongoimport --jsonArray -d blog -c posts --drop a.json                                                                                  [11:08:30]

      On 2.6

      mongoimport --jsonArray -d blog -c posts --drop a.json                                                                                  [11:05:45]

      More importantly than that this is causing a massert log entry on the server:
