Subject need some help understanding NN quorum edit log
Date Tue, 23 Oct 2012 22:31:49 GMT
Hi devs,
I am reading through the HA code, trying to understand how the
editlogs propagate.

I have looked at the following classes
EditLogTailer
JournalNode
QuorumJournalManager
NameNode
FSNameSystem

I see FSNameSystem is using FSImage editlog.   where is the tie-in
between  NN and  QuorumJournal?

thanks
