Re: High CPU utilization after storm node failover

2014-08-06 Thread Bobby Evans
+1 for failure testing. We have used other similar tools in the past to simulate different situations like network cuts, high packet loss, etc. I would love to see more of this happen, and the scheduler get smart enough to detect these situations and deal with them. - Bobby From: P. Taylor

Re: The role of supervisor in Storm

2014-07-07 Thread Bobby Evans
