BELUGA BEHR updated HIVE-21245:
-------------------------------
Description:
For all intents and purposes, it already is:
{code:java|title=HiveSessionImpl.java}
private static final String FETCH_WORK_SERDE_CLASS =
"org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe";
@Override
public HiveConf getHiveConf() {
sessionConf.setVar(HiveConf.ConfVars.HIVEFETCHOUTPUTSERDE,
FETCH_WORK_SERDE_CLASS);
return sessionConf;
}
{code}
https://github.com/apache/hive/blob/master/service/src/java/org/apache/hive/service/cli/session/HiveSessionImpl.java#L489-L492
The current default is:
{code}
// Serde for FetchTask
HIVEFETCHOUTPUTSERDE("hive.fetch.output.serde",
"org.apache.hadoop.hive.serde2.DelimitedJSONSerDe",
"The SerDe used by FetchTask to serialize the fetch output."),
{code}
Ultimately, I'd like to get rid of
{{org.apache.hadoop.hive.serde2.DelimitedJSONSerDe}} altogether. It's a weird
thing.
