If I I understand your question correctly, you can run "hadoop dfsadmin
-saveNamespace" on
your secondary namenode to force updates (which will be propagated to the
primary namenode
after completion). In order to do that you need to be in "safe mode" (by
running
"hadoop dfsadmin -safemode get").
I hope this helps...
