Ari Rabkin commented on CHUKWA-447:
-----------------------------------
Interesting. And sort of surprising, since both are spawning processes in a loop. Increased
50% is how large an increase in absolute terms?
> Load increased by 50% when using ExecAdaptor instead of org.apache.hadoop.chukwa.inputtools.plugin.metrics.Exec+FileTailingAdaptor

> While I am coming up a fix for CHUKWA-446, I notice the load average increased by ExecAdaptor.
There is probably something that could be improved to reduce the cost of ExecAdaptor.
