<div dir="ltr">Hi all,<div>We're seeing issues with using clusters consisting of multiple nodes today. Launch of clusters with >=3 nodes fails, with report of being unable to assign aliases to nodes other than "master". The same problem is seen with addnode. Adding one node is fine, but adding more than one gives the alias problem again. Terminating these clusters fails due to the missing alias as well, you have to use the ec2toolkit to shut down the offending nodes that were not named.</div>
<div><br></div><div>I'm on the latest developmental version, and I've noticed that there's a lot of gibberish in the node user data (as viewed through the web console) as of today.</div><div><br></div><div>Debug at the end, and thanks for the help.</div>
