Subject [jira] Commented: (HADOOP-952) Create a public (shared) Hadoop EC2 AMI
Date Tue, 13 Feb 2007 22:26:06 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-952?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12472903

James P. White commented on HADOOP-952:
---------------------------------------

I've applied the v3 patch and tried out the new AMI which successfully ran the "pi" example.

Had some trouble getting the SSH settings right again.  I need env.sh to look like this:

# Location of EC2 keys.
# The default setting is probably OK if you set up EC2 following the Amazon Getting Started
guide.
EC2_KEYDIR=`dirname "$EC2_PRIVATE_KEY"`

# The EC2 key name used to launch instances.
# The default is the value used in the Amazon Getting Started guide.
KEY_NAME=gsg-keypair

# Where your EC2 private key is stored (created when following the Amazon Getting Started
guide).
PRIVATE_KEY_PATH=`echo "$EC2_KEYDIR"/"id_rsa-$KEY_NAME"`

# SSH options used when connecting to EC2 instances.
SSH_OPTS=`echo -i "$PRIVATE_KEY_PATH" -o StrictHostKeyChecking=no`

The reason for the 'echo ...` business is that I need paths with embedded spaces to work.

Also I really think 'run-hadoop-cluster' should be split in two.  The part where it waits
for DynDNS to be set up should simply end and have the second part be a seperate script. 
A user with a new set up would also be advised to run "login-hadoop-cluster" before running
the second part to verify the settings.

> HADOOP-884 makes it easy to run Hadoop on an EC2 cluster, but building an AMI (Abstract
Machine Image) can take a little while. Amazon EC2 supports shared AMIs (http://developer.amazonwebservices.com/connect/entry.jspa?entryID=530&ref=featured),
so we could provide publically available AMIs for each Hadoop release.
