I'm including the text I responded in the issue as follows:

It sounds like you have some other package which depends on a specific version of python-urllib3 + RHEL's backported security fixes. Unfortunately, I can't force Curator to use plugins from the official RHEL repository.

I am obliged to ship updated plugins for whatever Curator depends on in the Elasticsearch repository. This is for security reasons. If there are collisions, you'll have to do some manual work to install using other repositories.

The reason you're getting conflicts is that the Elasticsearch repository has newer versions of the plugins available, and yum/rpm wants to use the newest by default. Curator should work with the older versions, but I can't put old versions of the plugins in the repository just to satisfy RHEL/CentOS.

My recommendation is to remove the Elasticsearch Curator repository and use the default repository. If there are dependencies not met, install each manually until Curator works.

This is why I recommend using pip instead of packages in the official documentation. It saves a lot of headache in this vein.
