Yuming Wang updated SPARK-27686:
--------------------------------
    Description: 
The built-in Hive 2.3 fixes the following issues:
 * HIVE-6727: Table level stats for external tables are set incorrectly.
 * HIVE-15653: Some ALTER TABLE commands drop table stats.
 * SPARK-12014: Spark SQL query containing semicolon is broken in Beeline.
 * SPARK-25193: insert overwrite doesn't throw exception when drop old data 
fails.
 * SPARK-25919: Date value corrupts when tables are "ParquetHiveSerDe" 
formatted and target table is Partitioned.
 * SPARK-26332: Spark sql write orc table on viewFS throws exception.
 * SPARK-26437: Decimal data becomes bigint to query, unable to query.

We need update migration guide.
