> Key: HIVE-17696

> Project: Hive

> Reporter: Vihang Karajgaonkar

> Attachments: HIVE-17696.2.patch, HIVE-17696.patch

>
> This is the code snippet from {{VectorizedParquetRecordReader.java}}
> {noformat}
> MessageType tableSchema;
> if (indexAccess) {
> List<Integer> indexSequence = new ArrayList<>();
> // Generates a sequence list of indexes
> for(int i = 0; i < columnNamesList.size(); i++) {
> indexSequence.add(i);
> }
> tableSchema = DataWritableReadSupport.getSchemaByIndex(fileSchema,
> columnNamesList,
> indexSequence);
> } else {
> tableSchema = DataWritableReadSupport.getSchemaByName(fileSchema,
> columnNamesList,
> columnTypesList);
> }
> indexColumnsWanted =
> ColumnProjectionUtils.getReadColumnIDs(configuration);
> if (!ColumnProjectionUtils.isReadAllColumns(configuration) &&
> !indexColumnsWanted.isEmpty()) {
> requestedSchema =
> DataWritableReadSupport.getSchemaByIndex(tableSchema,
> columnNamesList, indexColumnsWanted);
> } else {
> requestedSchema = fileSchema;
> }
> this.reader = new ParquetFileReader(
> configuration, footer.getFileMetaData(), file, blocks,
> requestedSchema.getColumns());
> {noformat}
> Couple of things to notice here:
> Most of this code is duplicated from {{DataWritableReadSupport.init()}}
> method.
> the else condition passes in fileSchema instead of using tableSchema like we
> do in DataWritableReadSupport.init() method. Does this cause projection
> columns to be missed when we read parquet files? We should probably just
> reuse ReadContext returned from {{DataWritableReadSupport.init()}} method
> here.
