If you build and start presto locally, you can append the function-namespace-managers plugin into the plugin.bundles in the config.properties.

`plugin.bundles=\

…/presto-function-namespace-managers/pom.xml, `

The function namespace managers is ready to use, I just happened to use it a few weeks ago. The key point is making presto server load the plugin, otherwise we would see a failure of ‘No factory for function namespace manager mysql’ as you reported.

SO I get the newest code from the master branch and run the presto in the IDE and config an function namespace example file according to the office docs: The the plugin.bundles have been added to the config.properties by default. And I got another error: What can caused this problem?

Or is there any wrong action I made when I wrote the configuration file or start the presto? And do anyone have a more detailed configuration guide to set up the Function Namespace Managers ?
