I tested with nearly the same setup regarding nsswitch.conf and hosts (my
foo-host points to another cluster-node so there is no NATing) and ist works:
nsswitch.conf:
	n-1 # bpsh 0 cat /etc/nsswitch.conf 
	passwd: files bproc
	shadow: files
	group: files
	hosts: files bproc
hosts:
	n-1 # bpsh 0 cat /etc/hosts
	127.0.0.1       localhost
	10.0.4.1        m-1
	10.0.4.10       m0
	10.0.4.11       m1
do the ping:
	n-1 # bpsh 0 ping -c 1 m1
	PING m1 (10.0.4.11): 56 octets data
	64 octets from 10.0.4.11: icmp_seq=0 ttl=64 time=0.1 ms

	--- m1 ping statistics ---
	1 packets transmitted, 1 packets received, 0% packet loss
	round-trip min/avg/max = 0.1/0.1/0.1 ms

(bproc-3.2.6)

Do you have /etc/protcols with the needed entries on the nodes -- I see
"unknown protocol icmp"-errors if it's missing -- but who knows ...
