    So I checked, and I do have those environment variables set, except for 
```RESMGR_HOME``` e.g., 
    
    ```
    LMC-053601:oodt mattmann$ echo $FILEMGR_HOME
    /usr/local/bigtranslate/filemgr
    LMC-053601:oodt mattmann$ echo $FILEMGR_URL
    http://localhost:9000
    LMC-053601:oodt mattmann$ 
    LMC-053601:oodt mattmann$ echo $RESMGR_URL
    http://localhost:9002
    LMC-053601:oodt mattmann$ 
    ```
    
    I was thinking about your code - is it that if an environment variable from 
local config isn't that set - you are publishing a null value to ZK or there is 
a getPropertyOrNull call somewhere that is causing this? If so, we should 
probably have a sensibleDefaults() configuration which are all the sensible 
defaults in case the environment is Null. Even better would be to use PathUtils 
in o.a.cas.metadata.util to do EnvVarOrMetadata replacement on all paths you 
read from config.

> 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.
