----------------------------------
Summary: Introduce the concept of default value to schema
Key: SPARK-23210
URL: https://issues.apache.org/jira/browse/SPARK-23210
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.2.1
Reporter: LvDongrong
There is no concept of DEFAULT VALUE for schema in spark now.
Our team want to support insert into serial columns of table,like "insert into
(a, c) values ("value1", "value2") for our use case, but the default vaule of
column is not definited. In hive, the default vaule of column is NULL if we
don't specify.
So I think maybe it is necessary to introduce the concept of default value to
schema in spark.
