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.
