From 334c5bd1ae50ac76770e545cab302361673f45de Mon Sep 17 00:00:00 2001 From: Florian Verhein <florian.verhein@gmail.com> Date: Sat, 7 Mar 2015 12:56:59 +0000 Subject: [PATCH] [SPARK-5641] [EC2] Allow spark_ec2.py to copy arbitrary files to cluster Give users an easy way to rcp a directory structure to the master's / as part of the cluster launch, at a useful point in the workflow (before setup.sh is called on the master). This is an alternative approach to meeting requirements discussed in https://github.com/apache/spark/pull/4487 Author: Florian Verhein <florian.verhein@gmail.com> Closes #4583 from florianverhein/master and squashes the following commits: 49dee88 [Florian Verhein] removed addition of trailing / in rsync to give user this option, added documentation in help 7b8e3d8 [Florian Verhein] remove unused args 87d922c [Florian Verhein] [SPARK-5641] [EC2] implement --deploy-root-dir --- ec2/spark_ec2.py | 42 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) diff --git a/ec2/spark_ec2.py b/ec2/spark_ec2.py index dabb9fce40..b6e7c4c2af 100755 --- a/ec2/spark_ec2.py +++ b/ec2/spark_ec2.py @@ -159,6 +159,15 @@ def parse_args(): "--spark-ec2-git-branch", default=DEFAULT_SPARK_EC2_BRANCH, help="Github repo branch of spark-ec2 to use (default: %default)") + parser.add_option( + "--deploy-root-dir", + default=None, + help="A directory to copy into / on the first master.
