Question about namenode HA
Hi Todd and other HA experts,

I've two question:

1) why the zkfc is a seperate process, i mean, what's the primary design consideration that we didn't integrate zkfc features into namenode self ?

2) If i deploy CDH4.1(included QJM feature),  since QJM can do fencing writer,  so can i just config like this safely ?
