      The list of documents below contains a duplicate _id. mongoimport correctly flags this as an error, but claims the document was imported into the collection.

      $ cat export.js
{ "_id" : { "$oid" : "53c833593206b4df88d74ca7" }, "x" : "a" }
{ "_id" : { "$oid" : "53c833593206b4df88d74ca7" }, "x" : "b" }
{ "_id" : { "$oid" : "53c833593206b4df88d74ca8" }, "x" : "c" }
{ "_id" : { "$oid" : "53c833593206b4df88d74ca9" }, "x" : "d" }
$ mongoimport --version
mongoimport version: 2.7.8
$ mongoimport --drop  -d test -c foo < export.js
