Re-reading this, I think it is dead, unless there is an update triggered by
this.
I *think* I have the resolution to the update issue.
Post `777` and parser extensions, extensions can / will be deployed through
the ui.
A script parser will deploy scripts, as we do grok rules to a directory, we
can have the deployment *also* make an entry in zookeeper with the checksum of
the script or some such. __That__ can be the item that is in zookeeper and
monitored for change. If we deploy a new version of the script by installing
it in the UI, it will save it to hdfs, and the change the entry in zookeeper,
triggering reload.
If this PR *is* dead, I may take this up
