Mongoimport of json file

Question

I have a json file consisting of about 2000 records   Each record which will correspond to a document in the mongo database is formatted as follows    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  new Date  Fri May 11 15 05 42 2012    startTime  new Date  Thu May 31 15 59 39 2012    numCores  64   sizeT  bss  1881400168  text  239574  data  22504       Each record is on a single line in the JSON file  and the only line breaks are at the end of every record   Therefore  each line in the document starts with   jobID       I am trying to import these into a mongo database using the following command   mongoimport --db dbName --collection collectionName --file fileName json   However  I get the following error   Sat Mar  2 01 26 12 Assertion  10340 Failure parsing JSON string near   execModif 0x10059f12b 0x100562d5c 0x100562e9c 0x10025eb98 0x10000e643 0x100010b60 0x10055c4cc 0x1000014b7     0x100001454   0   mongoimport                         0x000000010059f12b  ZN5mongo15printStackTraceERSo   43  1   mongoimport                         0x0000000100562d5c  ZN5mongo11msgassertedEiPKc   204  2   mongoimport                         0x0000000100562e9c  ZN5mongo11msgassertedEiRKSs   12  3   mongoimport                         0x000000010025eb98  ZN5mongo8fromjsonEPKcPi   1576  4   mongoimport                         0x000000010000e643                                                     ZN6Import8parseRowEPSiRN5mongo7BSONObjERi   2739  5   mongoimport                         0x0000000100010b60  ZN6Import3runEv   7376  6   mongoimport                         0x000000010055c4cc  ZN5mongo4Tool4mainEiPPc   5436  7   mongoimport                         0x00000001000014b7 main   55  8   mongoimport                         0x0000000100001454 start   52 Sat Mar  2 01 26 12 exception BSON representation of supplied JSON is too large  Failure parsing         JSON string near   execModif Sat Mar  2 01 26 12  Sat Mar  2 01 26 12 imported 0 objects Sat Mar  2 01 26 12 ERROR  encountered 1941 errors   I do not know what the problem is  Can someone recommend a solution

In windows you can use your Command Prompcmd cmd , in Ubuntu you can use your terminal by typing the following command:

mongoimport  -d  your_database_name  -c  your_collection_name  /path_to_json_file/json_file_name.json

then when you open your mongo shell, you will find to check your database_name when running this command:

show databases

Run the import command in another terminal   not inside mongo shell    mongoimport --db test --collection user --drop --file   downloads user json

If you try to export this test collection    gt  db test find       id    ObjectId  5131c2bbfcb94ddb2549d501     field     Sat Mar 02 2013 13 13 31 GMT 0400      id    ObjectId  5131c2d8fcb94ddb2549d502     field    ISODate  2012-05-31T11 59 39Z      with mongoexport  the first date created with Date      and the second one created with new Date       if use ISODate      will be the same as in the second line   so mongoexport output will be looks like this       id        oid     5131c2bbfcb94ddb2549d501      field     Sat Mar 02 2013 13 13 31 GMT 0400        id        oid     5131c2d8fcb94ddb2549d502      field        date    1338465579000       So you should use the same notation  because strict JSON doesn t have type Date   lt date gt      Also your JSON is not valid  all fields name must be enclosed in double quotes  but mongoimport works fine without them   You can find additional information in mongodb documentation and here

A bit late for probable answer  might help new people  In case you have multiple instances of database   mongoimport --host  lt host name gt   lt host port gt  --db  lt database name gt  --collection  lt collection name gt   --file  lt path to dump file gt  -u  lt my user gt  -p  lt my pass gt    Assuming credentials needed  otherwise remove this option

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
