[StarCluster] New Behavior: starcluster addnode error from StarCluster-created master instance

[MacMullan, Hugh]

That is a huge hassle! But it works. ;) I need to rewrite a bunch of scripts (that normally just do `pip install starcluster`). Thanks so much Vasisht.

I think it’s an issue with the latest version of boto. Are you using boto-2.33? Downgrading to boto-2.32.0 resolved the issue.

Change the boto version in setup.py and reinstall StarCluster (boto==2.32.0)

Hi Starcluster Friends!



Just today I heard from a user that he was having trouble adding nodes from the master of a StarCluster created cluster. The AMI is StarCluster public 64-bit Ubuntu EBS non-HVM (ami-765b3e1f in us-east-1). These instances have been working reliably this way for many months, so it seems like something has changed at AWS? Anyone know of anything?



Running default StarCluster 0.95.5

The behavior: locally (not from in EC2) I can add nodes just like normal. From the master, I get this:

$ starcluster an mycluster -a node001

Any thoughts? Anyone else seeing this?
