Frank McQuillan updated MADLIB-1109:
------------------------------------
Description:
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.
> Do not fail certain modules when optimizer_control GUC is set to off in
