amazon ec2 - Trouble Uploading Large Files to RStudio using Louis Aslett's AMI on EC2

Question

After following this simple tutorial http://www.louisaslett.com/RStudio_AMI/ and video guide http://www.louisaslett.com/RStudio_AMI/video_guide.html I have setup an RStudio environment on EC2.

The only problem is, I can't upload large files (> 1GB).

I can upload small files just fine.

When I try to upload a file via RStudio, it gives me the following error:

Unexpected empty response from server

Does anyone know how I can upload these large files for use in RStudio? This is the whole reason I am using EC2 in the first place (to work with big data).

Answer 1

Ok so I had the same problem myself and it was incredibly frustrating, but eventually I realised what was going on here. The default home directory size for AWS is less than 8-10GB regardless of the size of your instance. As this as trying to upload to home then there was not enough room. An experienced linux user would not have fallen into this trap, but hopefully any other windows users new to this who come across this problem will see this. If you upload into a different drive on the instance then this can be solved. As the Louis Aslett Rstudio AMI is based in this 8-10GB space then you will have to set your working directory outside this, the home directory. Not intuitively apparent from Rstudio server interface. Whilst this is an advanced forum and this is a rookie error I am hoping no one deletes this question as I spent months on this and I think someone else will too. I hope this makes sense to you?
