Mongodb Sharding not working - what is causing Collection not sharded - mongodb

Question

I am trying to set up mongodb sharding with two nodes. I have enabled 3 configuration process and a router process. I am extracting data (With 50 columns - 650 MB - _id as the key) from SQL server and putting in mongodb. In the pentaho configuration I have enabled "Use all Replica sets" and enter the primary node's host name and the port. When I run the transformation, all the data are getting into primary node and the other node is not getting data. When I entered, db.table.getShardDistribution(), I get the following message "Collection not sharded".
Also the status of is.BalancerRunning() gives me false status. I am very sure that background process balancer is not working here.
Mean while i tried to insert a sample test records 10,00,000 records with name as the key , the sharding setup was working fine and each shard got data distributed.
So,I am missing something or doing something wrong while I run pentaho transformation to populate data in mongodb. Any help is appreciated.

I am not sure from your post if you shard database and collections.
Once you setup shards did you enable sharding for database. like below
db.runCommand({
enablesharding : "dbname"
});
Do db.stats() to confirm.
After enable sharding for collections. like below.
db.runCommand({
shardcollection : "collection_name",
key : {
shardKey : "hashed"
}
});
Then to confirm db.collections.stats()
