    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.
