Terry Kim created SPARK-35225:
---------------------------------
Summary: EXPLAIN command should handle empty output of an analyzed
plan
Key: SPARK-35225
URL: https://issues.apache.org/jira/browse/SPARK-35225
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.2.0
Reporter: Terry Kim
Currently, EXPLAIN command puts an empty line if there is no output for an
analyzed plan. For example,
{code:java}
sql("CREATE VIEW test AS SELECT 1").explain(true)
{code}
produces:
{code:java}
== Parsed Logical Plan ==
'CreateViewStatement [test], SELECT 1, false, false, PersistedView
+- 'Project [unresolvedalias(1, None)]
+- OneRowRelation
== Analyzed Logical Plan ==
CreateViewCommand `default`.`test`, SELECT 1, false, false, PersistedView, true
+- Project [1 AS 1#7]
+- OneRowRelation
== Optimized Logical Plan ==
CreateViewCommand `default`.`test`, SELECT 1, false, false, PersistedView, true
+- Project [1 AS 1#7]
+- OneRowRelation
== Physical Plan ==
Execute CreateViewCommand
+- CreateViewCommand `default`.`test`, SELECT 1, false, false,
PersistedView, true
+- Project [1 AS 1#7]
+- OneRowRelation
{code}
