Gang Wu resolved PARQUET-2219. ------------------------------ Resolution: Fixed > ParquetFileReader throws a runtime exception when a file contains only > headers and now row data > ----------------------------------------------------------------------------------------------- > > Key: PARQUET-2219 > URL: https://issues.apache.org/jira/browse/PARQUET-2219 > Project: Parquet > Issue Type: Bug > Components: parquet-mr > Affects Versions: 1.12.1 > Reporter: chris stockton > Assignee: Gang Wu > Priority: Minor > > Google BigQuery has an option to export table data to Parquet-formatted > files, but some of these files are written with header data only. When this > happens and these files are opened with the ParquetFileReader, an exception > is thrown: > {{RuntimeException("Illegal row group of 0 rows");}} > It seems like the ParquetFileReader should not throw an exception when it > encounters such a file. > https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/main/java/org/apache/parquet/hadoop/ParquetFileReader.java#L949 -- This message was sent by Atlassian Jira (v8.20.10#820010)
