wangyum opened a new pull request #23970: [SPARK-27054][BUILD][SQL] Remove the Calcite dependency
URL: https://github.com/apache/spark/pull/23970
## What changes were proposed in this pull request?
Calcite is only used for [runSqlHive](https://github.com/apache/spark/blob/02bbe977abaf7006b845a7e99d612b0235aa0025/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/HiveClientImpl.scala#L699-L705) when `hive.cbo.enable=true`([SemanticAnalyzer](https://github.com/apache/hive/blob/release-1.2.1/ql/src/java/org/apache/hadoop/hive/ql/parse/SemanticAnalyzerFactory.java#L278-L280)).
So we can disable `hive.cbo.enable` and remove Calcite dependency.
