> Remove duplicated Hive table schema parsing in DataWritableReadSupport
> ----------------------------------------------------------------------

> Key: HIVE-10016
> URL: https://issues.apache.org/jira/browse/HIVE-10016
> Project: Hive
> Issue Type: Sub-task
> Reporter: Dong Chen

> Attachments: HIVE-10016-parquet.patch, HIVE-10016.1-parquet.patch
>
>
> In {{DataWritableReadSupport.init()}}, the table schema is created and its
> string format is set in conf. When construct the
> {{ParquetRecordReaderWrapper}} , the schema is fetched from conf and parsed
> several times.
> We could remove these schema parsing, and improve the speed of
> getRecordReader a bit.
