From 1342d7e7164c2af3a757c2aff7c25d68e2d5fb8d Mon Sep 17 00:00:00 2001 From: Patrick Wendell Date: Tue, 2 Sep 2014 20:32:37 -0700 Subject: [PATCH] SPARK-3358: [EC2] Switch back to HVM instances for m3.X. During regression tests of Spark 1.1 we discovered perf issues with PVM instances when running PySpark. This reverts a change added in #1156 which changed the default type for m3 instances to PVM. --- ec2/spark_ec2.py | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/ec2/spark_ec2.py b/ec2/spark_ec2.py index 7e25df57ee45b..eed6eb8485183 100755 --- a/ec2/spark_ec2.py +++ b/ec2/spark_ec2.py @@ -234,10 +234,10 @@ def get_spark_ami(opts): "cg1.4xlarge": "hvm", "hs1.8xlarge": "pvm", "hi1.4xlarge": "pvm", - "m3.medium": "pvm", - "m3.large": "pvm", - "m3.xlarge": "pvm", - "m3.2xlarge": "pvm", + "m3.medium": "hvm", + "m3.large": "hvm", + "m3.xlarge": "hvm", + "m3.2xlarge": "hvm", "cr1.8xlarge": "hvm", "i2.xlarge": "hvm", "i2.2xlarge": "hvm",
