We have a kubernetes cluster which has a dropwizard based web application running as a service. This application has a rest uri to upload files. It cannot upload files larger than 1MB. I get the following error:
ERROR [2017-07-27 13:32:47,629] io.dropwizard.jersey.errors.LoggingExceptionMapper: Error handling a request: ea812501b414f0d9

Also, I have tried using the configMap without any success. we are using kubernetes version 1.5. Please let me know if you need additional information.
Had this on my setup as well. Two advices here:
1: switch to official kubernetes nginx ingress, it's awesome (https://github.com/kubernetes/ingress/tree/master/controllers/nginx)
2: with the above ingress, you can add an annotation to your Ingresses to controll body size limit on per ingress basis like this :
annotations:
ingress.kubernetes.io/proxy-body-size: 10mworks great
