Subject [jira] [Commented] (SPARK-1805) Error launching cluster when master and slave machines are of different virtualization types
Date Mon, 09 Feb 2015 22:57:35 GMT

    [ https://issues.apache.org/jira/browse/SPARK-1805?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14313079#comment-14313079

Nicholas Chammas commented on SPARK-1805:
-----------------------------------------

I've created a PR to catch this error early.

We can create a separate PR later to actually support launching clusters where the master
and slaves have different virtualization types.

> In the current EC2 script, the AMI image object is loaded only once. This is OK when
the master and slave machines are of the same virtualization type (pv or hvm). But this won't
work if, say, the master is pv and the slaves are hvm since the AMI is not compatible across
these two kinds of virtualization.
