Subject [jira] Resolved: (HADOOP-6393) Allow master to run on larger EC2 instance
Date Wed, 06 Jan 2010 18:33:54 GMT

]

Tom White resolved HADOOP-6393.
-------------------------------

    Resolution: Not A Problem

I realized that this is actually already supported as long as you launch the master separately:

{code}
hadoop-ec2 launch-master --instance-type=c1.xlarge my-hadoop-cluster
hadoop-ec2 launch-slaves my-hadoop-cluster 10 # use the instance type set in the configuration
{code}

> Allow master to run on larger EC2 instance

> The namenode often needs more memory, so it would be useful to allow it to be run on
a different instance size.
