   This is a preplexing issue. The tests appear to pass on fresh Ubuntu18.04 
Docker Container on a better spec'd machine but fail on a lower spec'd machine. 
Commands to setup and execute the build and test are as follows:
   
   ```bash
   cd heron_root_dir
   docker/scripts/dev-env-create.sh heron-dev
   
   ./bazel_configure.py
   bazel build --config=ubuntu heron/...
   
   bazel test --config=ubuntu --test_output=errors --cache_test_results=no 
--test_verbose_timeout_warnings heron/...
   bazel test --config=ubuntu --test_output=all --cache_test_results=no 
--test_verbose_timeout_warnings heron/stmgr/tests/cpp/server:stmgr_unittest
   ```
   
   When I `cat` the `V1Controller.java` file in the containers terminal 
`loadPodFromTemplate` it is as it should be and wired up correctly in 
`createStatefulSet` on line 387. Could someone else please clone the repo and 
test if it passes the build? @joshfischer1108, @nicknezis, and anyone else who 
has some time, I could use an extra set of objective eyes on this. I am sure it 
is just something silly that got overlooked.
   
   I have also cleaned out the `loacPodFromTemplate` function and set it up to 
simple return a new/empty `V1PodTemplateSpec` to no avail on the more 
constrained system:
   
   ```java
     private V1PodTemplateSpec loadPodFromTemplate() {
   
       return new V1PodTemplateSpec();
     }
   ```
