[StarCluster] bug report for updated Starcluster release 0.94.3 - Windows 7

Thu Dec 12 12:13:38 EST 2013

Hello Justin
Many thanks for the reply.  That's helpful to know.  I've since been able to launch further clusters and have not had similar problems.

However, I am a bit unclear about how to install the latest version of starcluster under Windows 7 if an earlier version has already been installed. I thought that I had installed the latest version, but the old version number keeps appearing.

In brief, I downloaded the file starcluster-0.93.tar.gz and unzipped to a folder on my hard disk.  I then went to the folder and ran pip install startcluster [note that easy install starcluster didn't work previously - see another post].  Is there a different method for upgrading the version under Windows 7?  

Thanks
Emilia

Hi Emilia,

The exception occured because of a failure to properly fetch the
instance's userdata. I'm going to update the code to raise a better
error when this happens. If this happens again try waiting a few seconds
and re-running your start command and passing the --no-create (-x)
option. That will re-use the existing cluster instances and try again.

Also, from the crash report you sent it looks like you're using 0.94.2.
Could you please double check the version you're using and try upgrading
again if it's not 0.94.3? Thanks!

~Justin
