-------------------------------------
Summary: Fix Union query error message indentation
Key: SPARK-15265
URL: https://issues.apache.org/jira/browse/SPARK-15265
Project: Spark
Issue Type: Bug
Reporter: Dongjoon Hyun
Priority: Trivial
This issue fixes the error message indentation consistently with other set
queries (EXCEPT/INTERSECT).
**Before**
{code}
scala> sql("(select 1) union (select 1, 2)").head
org.apache.spark.sql.AnalysisException:
Unions can only be performed on tables with the same number of columns,
but one table has '2' columns and another table has
'1' columns;
{code}
**After**
{code}
scala> sql("(select 1) union (select 1, 2)").head
org.apache.spark.sql.AnalysisException: Unions can only be performed on tables
with the same number of columns, but one table has '2' columns and another
table has '1' columns;
{code}
**Reference**
EXCEPT / INTERSECT uses one-line format like the following.
{code}
scala> sql("(select 1) intersect (select 1, 2)").head
org.apache.spark.sql.AnalysisException: Intersect can only be performed on
tables with the same number of columns, but the left table has 1 columns and
the right has 2;
{code}
