Summary: Invalid filteredRowCount in InternalParquetRecordReader Key: PARQUET-1765 URL: https://issues.apache.org/jira/browse/PARQUET-1765 Project: Parquet Issue Type: Bug Components: parquet-mr Affects Versions: 1.11.0 Reporter: Gabor Szadovszky Assignee: Gabor Szadovszky Fix For: 1.11.1 The [record count|https://github.com/apache/parquet-mr/blob/apache-parquet-1.11.0/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/InternalParquetRecordReader.java#L185] is retrieved before setting the [projection schema|https://github.com/apache/parquet-mr/blob/apache-parquet-1.11.0/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/InternalParquetRecordReader.java#L188] so the value might be invalid if the projection impacts the filter. In normal cases it does not cause any issue because the record filter will filter correctly only that we are filtering the records one-by-one instead of dropping the related pages. -- This message was sent by Atlassian Jira (v8.3.4#803005)
