New question #261634 on Graphite:
https://answers.launchpad.net/graphite/+question/261634

I have a very simple Graphite setup and trying it out for the first time. Just 1-node, carbon-cache running. When I send data points (simple-text protocol being used). Whisper files are getting created however no data points get written due to the following errors seen in carbon logs. I have tried deleting whisper files but cannot seem to get around this issue. Any help is greatly appreciated.

More details on my setup..
I used pip to install whisper, carbon and graphite-web on CentOS 7. I have not modified any default configurations in carbon.conf. 

python-whisper-0.9.12-4.el7.noarch
graphite2-1.2.2-5.el7.x86_64
python-carbon-0.9.12-7.el7.noarch
