Transaction not found on remote peer - hyperledger

Question

I'm trying to setup simple blockchain network with Hyperledger fabric v1.0 on 2 instances.
My scenario
Instance A: Orderer and Peer0
Instance B: Peer1
I basically followed the "Use the native binaries" section of "Getting Started" page.
What I tried is I started 1 orderer and 1 peer on instanceA.
I installed, instantiated, invoked and made a query the example chaincode.
Then I started 1 peer on instanceB.
I could let peer1 on instanceB join my channel from instanceA. I could install the chaincode on peer1 from instanceA.
But I could not execute query peer1 from instanceA.
I can see at least chaincode installed on instanceB.
Error message is:
Error: Error endorsing query: rpc error: code = 2 desc = failed to obtain cds for mycc - transaction not found mycc/mychannel1
Below are commands I tried...
[InstanceA terminal1] 1. generate orderer.block
$ configtxgen -profile SampleSingleMSPSolo -outputBlock orderer.block
[InstanceA terminal2] 2. start orderer
$ CORE_PEER_LOCALMSPID=DEFAULT CORE_LOGGING_LEVEL=DEBUG ORDERER_GENERAL_LISTENADDRESS=0.0.0.0 ORDERER_GENERAL_GENESISMETHOD=file ORDERER_GENERAL_GENESISFILE=./orderer.block

$ CORE_PEER_ADDRESS=instanceB:7051 peer chaincode query -o 127.0.0.1:7050 -C mychannel1 -n mycc -c '{"Args":["query","a"]}'
I got errors like below. But I can see at least mycc chaincode on
instnceB and peer join command was completed successfully.
Error: Error endorsing query: rpc error: code = 2 desc = failed to obtain cds for mycc - transaction not found mycc/mychannel1
I'm using 2 ubuntu16.04 instances and not using docker or vagrant at all. I compiled binaries by make native.
Peer1 on instanceB may not connect orderer on instanceA because I saw the error log on peer1.
2017-04-08 23:42:14.903 UTC [deliveryClient] NewDeliverService -> ERRO 286 Cannot dial to 0.0.0.0:7050, because of grpc: timed out when dialing
Looks like peer1 tried to connect 0.0.0.0 instead of instanceA.
By the way I changed the Name of Organizations to DEFAULT from SampleOrg because I got errors like below otherwise.
2017-04-08 05:17:57.919 UTC [gossip/service] configUpdated -> ERRO 25e Tried joining channel mychannel1 but our org( DEFAULT ), isn't among the orgs of the channel: [SampleOrg] , aborting.
I think this may be because peer1 on instanceB was not linked to orderder on instanceA or transaction made by peer0 was not completed and reflected on instanceB. But I have no idea how to dig in...
Please give me help.
Thanks.

Answer 1

I finally solved my problem.
I turned out to be simple.
The solution was changing addresses of the orderer from 127.0.0.1:7050 to (IP Address of InstanceA):7050
common/configtx/tool/configtx.yaml
Orderer: &OrdererDefaults
# Orderer Type: The orderer implementation to start.
# Available types are "solo" and "kafka".
OrdererType: solo
Addresses:
# - 127.0.0.1:7050
- <IP Address of InstanceA>:7050
By doing this, Peer1 on instanceB start connecting orderer on instanceA.
It looks like "CORE_PEER_COMMITTER_LEDGER_ORDERER environmental parameter" and "-o option" were not used anymore or overwritten by configtx.yaml.
