MongoDB: insertion failure

[Yuri Gurevich]

Hi,

I'm trying to use BG with mongodb client, but I'm having some problem with data insertion:

java -cp build/bg.jar:db/MongoDB/lib/* edu.usc.bg.BGMainClass onetime -load -db  mongoDB.MongoDbClient -P ~/populateDB_new -p mongodb.url=127.0.0.1:27017 -p insertimage=true -p imagesize=2 -p threadcount=1 -p mongodb.database=local -p mongodb.writeConcern="none" -p maxexecutiontime=60

BGClient is in onetime mode.

*****max execution time specified : 60

BG Client: ThreadCount =1

Hi,

Please verify that you are creating a BG schema prior to issuing your command to populate the schema with data.  The following posting is relevant:

Thank you so much for your reply Shahram. 

You were right: I had some exception during schema creation phase.. Now I've added the missing parameter, and after that the schema was successfully created and the data has been loaded.

thanks,
