---------------------------------------

             Summary: Hive metastore filter-by-expression is broken for non-partition expressions
                 Key: HIVE-10122
                 URL: https://issues.apache.org/jira/browse/HIVE-10122
             Project: Hive
          Issue Type: Bug
            Reporter: Sergey Shelukhin


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
{noformat}
    // 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());
{noformat}

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] for info.
