Subject [jira] Commented: (HADOOP-952) Create a public (shared) Hadoop EC2 AMI
Date Mon, 19 Feb 2007 00:47:08 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-952?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12474051

James P. White commented on HADOOP-952:

I tried out the v4-tar scripts and they work fine.  The choice of the "start-" prefix was
reflecting that the cluster nodes were being started, but obviously your choice is fine.

One thing that might be worthwhile adding is a HADOOP_HOME setting in the AMI perhaps with
a PATH update too.  That could be with a "/root/hadoop-env.sh" file and/or a "/usr/local/hadoop-current"
symlink or the like.

I see how the HADOOP_VERSION in the local env.sh works and selects the right AMI, and maybe
avoiding the duplicate settings is the right thing, but with the way it is now it doesn't
"feel" like Hadoop is "installed" in the AMI.  But since I'm a cluster newbie. this may be
something I'll change my mind on.

And speaking of that, the Hadoop version thing being in those jar file names seems like a
problem too. 

Any notion what's wrong with my attempt to run "bin/hadoop jar hadoop-0.11.1-test.jar DFSCIOTest
-write "?

> 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.
