Evan Pollan updated WHIRR-488:
------------------------------
Attachment: whirr.jclouds.spotPriceHang.log
Here's how this behavior manifests itself in 0.7.0 and the trunk (see
whirr.jclouds.spotPriceHang.log).
It's worth noting that I have a cron job that checks to see if whirr is still
running launch-cluster 30 minutes after it was started. If so, it kills it,
waits 5 minutes, and tries to start the cluster again with the same properties.
~75% of the time, this works. If it hangs again, I edit the cluster
properties to use on-demand pricing, and it works 100% of the time.
The incidences of hangs are now in more than 50% of the time, BTW. Seems like
the problem is worse in 0.7.0+...

> Key: WHIRR-488
> URL: https://issues.apache.org/jira/browse/WHIRR-488
> Project: Whirr
> Issue Type: Bug
> Affects Versions: 0.6.0
> Environment: EC2, creating a cdh hadoop cluster
> Reporter: Evan Pollan
> Attachments: whirr.jclouds.spotPriceHang.log, whirr.startup.hang.log
>
>
> In about 1 out of every 5-7 attempts, whirr will hang while creating a
> spot-priced cluster in EC2. The process just sits there, consuming no system
> resources and writing nothing to stderr or stdout. In each case, some number
> of cluster nodes are up and running.
> This happened again to me today, and whirr was hung for about 4 hours. As
> usual, there were a bunch of errors logged while it was trying to create the
> instances. About 10 minutes in, though, whirr just went radio silent and
> stayed that way until I killed it.
> I'll attached the output -- it looks similar to the other instances where
> whirr has had this problem.
