------------------------------
Fix Version/s: (was: 2.1.1)
> Reset Command support reset specific property which is compatible with Hive
> ---------------------------------------------------------------------------
>
> Key: SPARK-21054
> URL: https://issues.apache.org/jira/browse/SPARK-21054
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.1.1
> Reporter: Wang Haihua
> Priority: Minor
>
> When we transfer our SQL in production from Hive to SparkSQL, we found some
> SQL like {{reset dfs.blocksize;}} will throw error in SparkSQL.
> We found cause is,
> after SPARK-15330, Spark 2.0.0 support Reset command which will Reset all
> properties and don't support {{reset key}}.
> But after Hive 2.1.1 (HIVE-14418), Hive also support Reset Command for
> specific property.
> SQL compatibility with Hive will ease user more, and lower the cost that
> transfer SQL from Hive to SparkSQL.
