--------------------------------
Summary: 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
Assignee: Dong Chen
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.
