Hi, all: I configured a hadoop cluster with 9 hosts, each with 2 VCPU and 4G Ram.
I noticed when I run the example pi program, only when I configure it with at least 8*9=72 mappers will all hosts be busy. Which means there is a default 8 mappers per host? How is this value decided? And where can I change it? Thanks very much!
