think of it as "internal coordinator"
it has no real consequences to the outside world
and we even have though about removing the "(master)"
output from SHOW results altogether already as it
doesn't really provide any useful information to
the user

the "master" role will fail over to one of the other
data nodes immediately
PS: i can see that you are using cluster with MySQL 5.1.15
which was an early pre-GA release. Cluster is no longer
maintained in the MySQL 5.1 release branch at all anymore,
you should now always use the MySQL Cluster 6.3 or 7.0
release branches
