Description:
Page: http://dev.mysql.com/doc/refman/5.5/en/mysql-cluster-thread-states.html

"Waiting for ndbcluster global schema lock" as seen on a 7.2 cluster is not in the list of documented cluster thread states.

How to repeat:
Compare possible thread states for ndb 7.2 with the documentation.

From the 5.6.21 (5.6 branch on Github) source:

$ grep proc_info.set\( sql/ndb_global_schema_lock.cc
      proc_info.set("Waiting for allowed to take ndbcluster global schema lock");
  proc_info.set("Waiting for ndbcluster global schema lock");

Seems like there are two states missing instead of one.
