Hi,

I am unable to start spark slaves from my master node. when I run
./start-all.sh in my master node it brings up the master and but fails for
slaves saying "permission denied public key" for slaves but I did add the
master id_rsa.pub to my slaves authorized_keys and I checked manually from

Thanks!

SSH problem

[Sai Prasanna]

Hi All,

I have a five node spark cluster, Master, s1,s2,s3,s4.

I have passwordless ssh to all slaves from master and vice-versa.
But only one machine, s2, what happens is after 2-3 minutes of my
connection from master to slave, the write-pipe is broken. So if try to
connect again from master i get the error,
ssh: Connect to host s1 port 22: Connection refused.
But i can login from s2 to master, and after doing it for next 2-3 min i
get access from master to s2.

What is this strange behaviour ?
I have set complete access in hosts.allow also !!
