[SPARK-1041] remove dead code in start script, remind user to set that in spark-env.sh the lines in start-master.sh and start-slave.sh no longer work in ec2, the host name has changed, e.g. ubuntu@ip-172-31-36-93:~$ hostname ip-172-31-36-93 also, the URL to fetch public DNS name also changed, e.g. ubuntu@ip-172-31-36-93:~$ wget -q -O - http://instance-data.ec2.internal/latest/meta-data/public-hostname ubuntu@ip-172-31-36-93:~$ (returns nothing) since we have spark-ec2 project, we don't need to have such ec2-specific lines here, instead, user only need to set in spark-env.sh You can merge this pull request into a Git repository by running: $ git pull https://github.com/apache/incubator-spark deadcode_in_sbin Alternatively you can review and apply these changes as the patch at: https://github.com/apache/incubator-spark/pull/588.patch ---- commit e4236e0c717e1ce7b6f91a83ce4c0cb7a4ae8046 Author: CodingCat <zhunans...@gmail.com> Date: 2014-02-12T18:24:34Z remove dead code in start script, remind user set that in spark-env.sh ----
