-----------------------------------
Resolution: Fixed
> MADLIB doesn't work with gp_distribution_policy changes in Greenplum 6
> ----------------------------------------------------------------------
>
> Key: MADLIB-1298
> URL: https://issues.apache.org/jira/browse/MADLIB-1298
> Project: Apache MADlib
> Issue Type: Bug
> Reporter: Heikki Linnakangas
> Priority: Major
> Fix For: v1.16
>
>
> Recent commits in Greenplum master branch - which will eventually become
> Greenplum 6 - changed the gp_distribution_policy catalog table's layout. See
> [https://github.com/greenplum-db/gpdb/commit/69ec6926c2284ff97d8b82282072b5b205e8aa27]
> and
> [https://github.com/greenplum-db/gpdb/commit/242783ae9f573bb03da3d89dc689c6743dfce510.]
>
> That broke get_distribution_policy() function, in utilities.py_in, because it
> looks at the renamed gp_distribution_policy.attrnums column. The recommended
> way to deparse the DISTRIBUTED BY clause of a table is now to use the new
> pg_catalog.pg_get_table_distributedby() helper function. MADLIB should use
> that too, when running against GPDB 6.
>
> (I'll open a pull request for this shortly)
