Apache Spark reassigned SPARK-35102:
------------------------------------
Assignee: Apache Spark
> Make spark.sql.hive.version meaningful and not deprecated
> ---------------------------------------------------------
>
> Key: SPARK-35102
> URL: https://issues.apache.org/jira/browse/SPARK-35102
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.2.0
> Reporter: Kent Yao
> Assignee: Apache Spark
> Priority: Minor
>
> Firstly let's take a look the definition and comment.
> {code:java}
> // A fake config which is only here for backward compatibility reasons. This
> config has no effect
> // to Spark, just for reporting the builtin Hive version of Spark to existing
> applications that
> // already rely on this config.
> val FAKE_HIVE_VERSION = buildConf("spark.sql.hive.version")
> .doc(s"deprecated, please use ${HIVE_METASTORE_VERSION.key} to get the Hive
> version in Spark.")
> .version("1.1.1")
> .fallbackConf(HIVE_METASTORE_VERSION)
> {code}
> It is used for reporting the built-in Hive version but the current status is
> unsatisfactory, as it is could be changed in many ways e.g. --conf/SET syntax.
> It is marked as deprecated but kept a long way until now. I guess it is hard
> for us to remove it and not even necessary.
> On second thought, it's actually good for us to keep it to work with the
> `spark.sql.hive.metastore.version`. As when
> `spark.sql.hive.metastore.version` is changed, it could just be used to
> report the compiled hive version statically, it's useful when an error occurs
> in this case. So this parameter should be fixed to compiled hive version.
