---------------------------------
What are the potential behavior changes this JIRA could introduce?
Based on the PR https://github.com/apache/spark/pull/20659, the risk is pretty
high.

> {{hive.classifier}} to {{core}}
> calcite.version from {{1.2.0-incubating}} to {{1.10.0}}
> datanucleus-core.version from {{3.2.10}} to {{4.1.17}}
> remove {{orc.classifier}}, it means orc use the {{hive.storage.api}}, see:
> ORC-174
> add new dependency {{avatica}} and {{hive.storage.api}}
> * ORC compatibility changes:

> * hive-thriftserver java file update:
> update {{sql/hive-thriftserver/if/TCLIService.thrift}} to hive 2.3.2
> update {{sql/hive-thriftserver/src/main/java/org/apache/hive/service/*}} to
> hive 2.3.2
> * TestSuite should update:
> ||TestSuite||Reason||
> |StatisticsSuite|HIVE-16098|
> |SessionCatalogSuite|Similar to [VersionsSuite.scala#L427|#L427]|
> |CliSuite, HiveThriftServer2Suites, HiveSparkSubmitSuite, HiveQuerySuite,
> SQLQuerySuite|Update hive-hcatalog-core-0.13.1.jar to
> hive-hcatalog-core-2.3.2.jar|
> |SparkExecuteStatementOperationSuite|Interface changed from
> org.apache.hive.service.cli.Type.NULL_TYPE to
> org.apache.hadoop.hive.serde2.thrift.Type.NULL_TYPE|
> |ClasspathDependenciesSuite|org.apache.hive.com.esotericsoftware.kryo.Kryo
> change to com.esotericsoftware.kryo.Kryo|
> |HiveMetastoreCatalogSuite|Result format changed from Seq("1.1\t1", "2.1\t2")
> to Seq("1.100\t1", "2.100\t2")|
> |HiveOrcFilterSuite|Result format changed|
> |HiveDDLSuite|Remove $ (This change needs to be reconsidered)|
> |HiveExternalCatalogVersionsSuite| java.lang.ClassCastException:
> org.datanucleus.identity.DatastoreIdImpl cannot be cast to
> org.datanucleus.identity.OID|
> * Other changes:
> Close hive schema verification:
> [HiveClientImpl.scala#L251|https://github.com/wangyum/spark/blob/75e4cc9e80f85517889e87a35da117bc361f2ff3/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/HiveClientImpl.scala#L251]
> and
> [HiveExternalCatalog.scala#L58|https://github.com/wangyum/spark/blob/75e4cc9e80f85517889e87a35da117bc361f2ff3/sql/hive/src/main/scala/org/apache/spark/sql/hive/HiveExternalCatalog.scala#L58]
> Update
> [IsolatedClientLoader.scala#L189-L192|https://github.com/wangyum/spark/blob/75e4cc9e80f85517889e87a35da117bc361f2ff3/sql/hive/src/main/scala/org/apache/spark/sql/hive/client/IsolatedClientLoader.scala#L189-L192]
> Because Hive 2.3.2's {{org.apache.hadoop.hive.ql.metadata.Hive}} can't
> connect to Hive 1.x metastore, We should use
> {{HiveMetaStoreClient.getDelegationToken}} instead of
> {{Hive.getDelegationToken}} and update {{HiveClientImpl.toHiveTable}}
> All changes can be found atÂ
> [PR-20659|https://github.com/apache/spark/pull/20659].
