Is there any Hadoop "Hook" / Interface if a configuration changes?

Hello,

 

We want to distribute the configuration via Zookeeper. The goal is that HDFS
Clients can access the (centralized) Hadoop configuration. 

Is there any event / signal . or something else, which is triggered, if the
configuration is changed on the NameNode? 

My ideas: This event could update the configuration which is stored and
distributed via Zookeeper.

 

Thanks Ralf
