[jira] [Commented] (KUDU-854) Add ability to set projections in python scan API

    [ https://issues.apache.org/jira/browse/KUDU-854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15475502#comment-15475502 ] 

Jordan Birdsell commented on KUDU-854:
--------------------------------------

The SetProjectedColumnNames method is exposed and accounted for in the unit tests.The SetProjectedColumnIndexes and GetProjectionSchema methods seem to be missing,. [~tlipcon], is that what this is intended to address?
