Dong Chen created HIVE-10031: -------------------------------- Summary: Modify the using of jobConf variable in ParquetRecordReaderWrapper constructor Key: HIVE-10031 URL: https://issues.apache.org/jira/browse/HIVE-10031 Project: Hive Issue Type: Sub-task Reporter: Dong Chen Assignee: Dong Chen
In {{ParquetRecordReaderWrapper}} constructor, it create splits, set projections and filters in conf, create task context, and then create Parquet record reader. In this procedure, we could improve the logic of conf usage: 1. the clone of jobConf is not necessary. This could speed up getRecordReader a little. 2. the updated jobConf is not passed to Parquet in one case. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
