Mongoimport of json file

try this,

mongoimport --db dbName --collection collectionName <fileName.json

Example,

mongoimport --db foo --collection myCollections < /Users/file.json
connected to: *.*.*.*
Sat Mar  2 15:01:08 imported 11 objects

Issue is because of you date format.

I used same JSON with modified date as below and it worked

{jobID:"2597401",
account:"XXXXX",
user:"YYYYY",
pkgT:{"pgi/7.2-5":{libA:["libpgc.so"],flavor:["default"]}},     
startEpoch:"1338497979",
runTime:"1022",
execType:"user:binary",
exec:"/share/home/01482/XXXXX/appker/ranger/NPB3.3.1/NPB3.3-MPI/bin/ft.D.64",
numNodes:"4",
sha1:"5a79879235aa31b6a46e73b43879428e2a175db5",
execEpoch:1336766742,
execModify:{"$date" : 1343779200000},
startTime:{"$date" : 1343779200000},
numCores:"64",
sizeT:{bss:"1881400168",text:"239574",data:"22504"}}

hope this helps

I was able to fix the error using the following query:

mongoimport --db dbName --collection collectionName --file fileName.json --jsonArray

Hopefully this is helpful to someone.

Using mongoimport you can able to achieve the same

mongoimport --db test --collection user --drop --file ~/downloads/user.json

where,

test - Database name
user - collection name
user.json - dataset file

--drop is drop the collection if already exist.
