-------------------------------------
Summary: sbin/slaves doesn't work when we use password
authentication for SSH
Key: SPARK-3584
URL: https://issues.apache.org/jira/browse/SPARK-3584
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.2.0
Reporter: Kousuke Saruta
In sbin/slaves, ssh command run in the background but if we use password
authentication, background ssh command doesn't work so sbin/slaves doesn't work.
Also I suggest improvement for sbin/slaves.
In current implementation, slaves file is trucked by Git but it can be edited
by user so we prepare slaves.template instead of slaves.
Default slaves file has one entry, localhost, so we should use localhost as a
default host list.
I modified sbin/slaves to choose localhost as a default host list.
