From cda2b150412314c47c2c24883111bfc441c3a3a2 Mon Sep 17 00:00:00 2001 From: Josh Rosen Date: Fri, 24 May 2013 13:05:06 -0700 Subject: [PATCH] Use ec2-metadata in start-slave.sh. PR #419 applied the same change, but only to start-master.sh, so some workers were still starting their web UI's using internal addresses. This should finally fix SPARK-613. --- bin/start-slave.sh | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/bin/start-slave.sh b/bin/start-slave.sh index 616c76e4ee..26b5b9d462 100755 --- a/bin/start-slave.sh +++ b/bin/start-slave.sh @@ -6,7 +6,8 @@ bin=`cd "$bin"; pwd` # Set SPARK_PUBLIC_DNS so slaves can be linked in master web UI if [ "$SPARK_PUBLIC_DNS" = "" ]; then # If we appear to be running on EC2, use the public address by default: - if [[ `hostname` == *ec2.internal ]]; then + # NOTE: ec2-metadata is installed on Amazon Linux AMI.
