I don’t know if I would say that… 

I read Marcelo’s question of “if the cluster is up, even though a RS may be 
down, can I still insert records in to HBase?”

So if the cluster is up, then you can insert records in to HBase even though 
you lost a RS that was handing a specific region. 

But because he talked about syncing nodes… I could be misreading his initial 
question…

The opinions expressed here are mine, while they may reflect a cognitive 
thought, that is purely accidental. 
Use at your own risk.
