Subject Re: Using zookeeper to assign a bunch of long-running tasks to nodes (without unhandled tasks and double-handled tasks)
Date Mon, 25 Jan 2010 07:05:35 GMT
Hi guys,

Let me ask a design/best practice question.

The design you guys are talking about seems to be p2p based, under what
circumstances is such design prefered to a master-based one(like
gfs,bigtable,hbase...)? Looks like for a full fledged system,a master is
needed anyway to carry out bookkeeping activities,  not mention it is simple
to design(no race condition,herd effect etc).


BTW is it a good practice to store indivdual node's monitoring metrics
inside Zookeeper with proactive refreshing(say every sec)?  Is this
considered as abuse?
