I am starting a postgres-xc server with two datanodes and one coordinator.
I used same parameter for both nodes but from one node I am getting the following error:

LOG:  could not bind IPv4 socket: LOG:  could not bind IPv4 socket: Address already in use
HINT:  Is another postmaster already running on port 5660? If not, wait a few seconds and retry.
WARNING:  could not create listen socket for "localhost"
FATAL:  could not create any TCP/IP sockets

and the other node gives me the following error

LOG:  autovacuum launcher started
ERROR:  PGXC Node datanode1: object already defined
STATEMENT:  CREATE NODE datanode1 WITH (TYPE = 'datanode', PORT = 15671)
LOG:  PGXC node datanode2: Applying default host value: localhost
STATEMENT:  CREATE NODE datanode2 WITH (TYPE = 'datanode', PORT = 15672)

Kindly share your inputs on this issues.
