Do I have to reformat the json ? is it possible to make it work like this ?

Answer 1

the first error message says:
warning: attempting to insert document with size 124.6 MB (exceeds 16.0 MB limit)
This implies you are trying to insert a document that is 124.6MB in size.
A json document starts with an open brace character "{" and ends with a closed brace character "}". The error message implies that you have 124.6MB between such characters.
I think you need to examine your input file and verify that each session object is defined as a separate document - another words starts and ends with a brace.
I suspect the problem is that the session objects are in fact embedded in a master document - sort of a container document. This would make mongoimport try to map the master container document to its collection - and not the session objects as you require.

Answer 2

First of all, for verifying that your GeoJSON file is accurate, you could use Geojsonlint, QGIS and so on.
After than, to import your data into your collection, use Mongoimport:
mongoimport --db MY_DATABASE_NAME -c MY_COLLECTION_NAME --type json --file "MY_GEOJSON_FILENAME"
Replace the 3 variables above whith your valid names. Obviously, make sure that your current directory contains the file.
Profit! :)
