> If the optimizer_control GUC is set to off in Greenplum, the following install checks will fail, and these MADlib functions will not work:  
> * decision tree
> * random forest
> * LDA
> * k-Means
> * PMML export for decision tree
> * PMML export for random forest
> There may be others, but these are the ones I am aware of. 
> The parameter optimizer_control 
> https://gpdb.docs.pivotal.io/43130/ref_guide/config_params/guc-list.html#optimizer_control
> controls whether the server configuration parameter optimizer 
> https://gpdb.docs.pivotal.io/43130/ref_guide/config_params/guc-list.html#optimizer
> can be changed. The parameter optimizer controls whether the GPORCA optimizer is enabled when running SQL queries.
