Re: [Postgres-xc-general] Add new coordinator error!

I can not just issue "add coordinator master",it alway asked me for more
here is my step:

# Deploy binaries
PGXC$ depoly all
#initialize everyting: one GTM Master, three GTM_Proxy, three
coordinator, three datanode
PGXC$ init all
....
PGXC$ Createdb pgxc
....
PGXC$ Psql
pgxc=# select * from pgxc_node; node_name | node_type | node_port |
node_host | nodeis_primary | nodeis_preferred | node_id
....
pgxc=# create table user_info_hash(id int primary key,firstname
text,lastname text,info text) distribute by hash(id);
NOTICE: CREATE TABLE / PRIMARY KEY will create implicit index
"user_info_hash_pkey" for table "user_info_hash"
CREATE TABLE
...
PGXC$ deploy node4
PGXC$ add datanode master datanode4
*ERROR: please specify the host for the datanode masetr*
PGXC$ add datanode master datanode4 node4 20008 /opt/pgxc/nodes/dn_master
*ERROR: sorry found some inconflicts in datanode master configuration.*
--------------------------------------------------------------


2.
and i found when the dump file contain table with

CREATE TABLE user_info_hash (
id integer NOT NULL,
firstname text,
lastname text,
info text
)
DISTRIBUTE BY HASH (id)
TO NODE (datanode1,datanode2,datanode3);

is alway failed to add new coordinator
but with this

CREATE TABLE user_id (
id integer NOT NULL
)
DISTRIBUTE BY HASH (id)
TO NODE (dn2,dn1,dn3);

it's sucessed to add the new coordinator to the cluster
