Summary: Update TextRecordReader
Key: HIVE-21303
URL: https://issues.apache.org/jira/browse/HIVE-21303
Project: Hive
Issue Type: Improvement
Components: Query Processor
Affects Versions: 4.0.0, 3.2.0
Reporter: BELUGA BEHR
Assignee: BELUGA BEHR
Attachments: HIVE-21303.1.patch
Remove use of Deprecated
{{org.apache.hadoop.mapred.LineRecordReader.LineReader}}
For every call to {{next}}, the code dives into the configuration map to see if
this feature is enabled. Just look it up once and cache the value.
{code:java}
public int next(Writable row) throws IOException {
...
if (HiveConf.getBoolVar(conf, HiveConf.ConfVars.HIVESCRIPTESCAPE)) {
return HiveUtils.unescapeText((Text) row);
}
return bytesConsumed;
}
{code}
Other clean up.
