how to change the hostname parameter value? from localhost to real ip address. (no replies)

Dear all:

My cluster's config.ini is using localhost for the parameter hostname.

And now, I want to add a new data node.then the NDBN part looks like as below.

[ndbd]
hostname=localhost
NodeId=3

[ndbd]
hostname=localhost
NodeId=4

[ndbd]
hostname=192.168.39.157
NodeId=5

[ndbd]
hostname=192.168.39.157
NodeId=6


the problem is,mgmd can't startup,and report an error:

2012-10-11 14:57:59 [MgmtSrvr] INFO -- Loaded config from '/usr/local/mysql/mysql-cluster/ndb_1_config.bin.3'
2012-10-11 14:57:59 [MgmtSrvr] ERROR -- at line 32: Mixing of localhost (default for [NDBD]HostName) with other hostname(compute-48-16.local) is illegal

2012-10-11 14:57:59 [MgmtSrvr] ERROR -- Could not load configuration from '/home/mysqlCluster/my_cluster/conf/config.ini'


I tried to change localhost to real ip addr,and the data node 3 can't startup either.
