no data after connecting to mongos (sharded cluster) #1447
Description
I setup a cluster with 3 Shards with MongoDB Cloud Manager,
When I migrated my database I migrated it to one shard instead of the whole cluster using the following connection string:
mongodb://user:pass@host1:27000,host2:27000,host3:27000/test-db?ReplicaSet=myShard_0
myShard_1 and myShard_2 are now empty with data size (4.0K)
now after I setup 3 mongos I tried to connect my application to the 3 mongos (connect it to the whole cluster
mongodb://user:pass@mongos1:27017,mongos2:27017,mongos3:27017/test-db
the connection has been accepted but my application (parse) can't gather data I receive this info "You have no classes yet"
Although mongos1 is hosted on the myshard_0
Why is this happening?

Could it be that _Schema is not being found because the data is on the wrong shard due to the way you migrated?
Perhaps you could try turning the mongo profiler fully on to see what is happening with queries, or try querying through mongos for _Schema and other special Parse collections to see if you can find data.
I don't think there is any official support for sharded clusters but it seems like it should just work.
