Wang Haihua created SPARK-21054:
-----------------------------------
Summary: 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
Fix For: 2.1.1
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 wich will Reset all
properties.
But after Hive 2.1.1 (HIVE-14418), Hive also support Reset Command for specific
property.
SQL compatibility with Hive will ease user more, lower the cost that transfer
SQL from Hive to SparkSQL.
