> OODT is made up of a number of different components, each of which have their own set
of configuration files and locations. This is complex to manage and causes additional problems
when the platform requires distribution across servers or geographically.
> To combat this we are proposing that we migrate the OODT configuration to an opional
Zookeeper module that would allow users to commission a zookeeper cluster and register the
various OODT components against it, which will allow the zookeeper cluster to maintain the
state of the various OODT components regardless of scale.
