Redshift Bulk Loader Hanging

[chudson]

Issue: Redshift Bulk Loader is failing to complete a 12gb write operation.

Probable Issue: Something has happened to our network over the last few days and the ISP and IT has stated that it has been resolved. I don't think it is.

This workflow has worked flawlessly up until last Friday when these issues occurred and only took about 15-20min to complete. I have been receiving errors here and there about 'unable to resolve hostname'. But, currently, it is just sitting at 100% failing to complete.

Reason for Post:

I want to confirm that no patch updates went through that might have caused these issues. Basically confirming this isn't Alteryx :D.

Thanks for any replies

I had something similar happen and what you may want to do is reboot your cluster on aws. there might be an unfinished job that is causing the lag. You can tell this is the case by going to the query editor and running a SELECT COUNT (*) FROM XYZ and if it just keeps going then you want to reboot the cluster also it may help to talk to AWS.

Thanks for the reply. It ended up being our internal network. Bad switch and IT misconfigured some cat cables. All good now.
