[jira] [Commented] (PARQUET-1341) Null count is suppressed when columns have no min or max and use unsigned sort order

["ASF GitHub Bot (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PARQUET-1341?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16526903#comment-16526903 ] 

ASF GitHub Bot commented on PARQUET-1341:
-----------------------------------------

rdblue opened a new pull request #499: PARQUET-1341: Fix null count stats in unsigned-sort columns.
URL: https://github.com/apache/parquet-mr/pull/499
 
 
   When a column is all nulls, it has no min and max values, causing it to be handled with the conversion from min and max (not the newer min_value and max_value). In that path, stats are suppressed if the column's expected sort order is not a signed order because the old code only used signed ordering.
   
   This PR always adds the null count, regardless of the handling for min and max or min_value and max_value.
