The current RC creation scripts rely on project poms having a plugin configured to handle nexus staging repository closing / dropping. The hbase-connectors project is currently missing this plugin, which makes it so that a RM has to go manually close the staging repository and then copy the location into the generated vote text.
the needed plugin config is:
<!-- this profile should match the name of the release profile in the root asf pom -->
<!-- This should insert itself in place of the normal deploy plugin and then
handle either closing or dropping the staging repository for us depending
on if the build succeeds.
