Hi,
I have imported the json file and 516784 was imported in to applicationData.products.
MongoDB Enterprise > use applicationData
switched to db applicationData
MongoDB Enterprise > show collections
products
MongoDB Enterprise > db.products.count()
516784
vagrant@m103:/dataset$ validate_lab_import_dataset
Incorrect number of documents imported - make sure you import the entire dataset.
… odd. 
anyway had the same issue for validation?
vagrant@m103:/dataset$ mongoimport --port=30000 --username=m103-application-user --password=m103-application-pass --authenticationDatabase=admin --db=applicationData --collection=products --file=/dataset/products.json

@suhank please delete your last post. It contains the answer to the lab. Remember… forum guidelines 
In addition, please also delete your duplicate thread -->
You imported the data into the wrong server. Use the host from the previous lab.
Hi @suhank,
Please make sure that you are running your mongod instance on the same port which you used in the previous Lab - Creating First Application User i.e. 27000.
Hope it helps!
Thanks,

Hi, Shubham,
Thanks for your email, the problem is caused by port number I was using 30000.
now it is good now.
thanks,
Hank
thanks a lot, I imported into 30000 instance.
