      Description

      See https://issues.apache.org/jira/browse/HIVE-10091?focusedCommentId=14382413&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14382413

      These two lines of code

          // Replace virtual columns with nulls. See javadoc for details.
          prunerExpr = removeNonPartCols(prunerExpr, extractPartColNames(tab), partColsUsedInFilter);
          // Remove all parts that are not partition columns. See javadoc for details.
          ExprNodeDesc compactExpr = compactExpr(prunerExpr.clone());
      

      are supposed to take care of this; I see there were bunch of changes to this code over some time, and now it appears to be broken.

      Thanks to Thejas M Nair for info.
