Dilip Biswal created SPARK-27480:
------------------------------------
Summary: Improve explain output of describe query command to show
the actual input query as opposed to a truncated logical plan.
Key: SPARK-27480
URL: https://issues.apache.org/jira/browse/SPARK-27480
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.4.1
Reporter: Dilip Biswal
Currently running explain on describe query gives a little confusing output.
Instead of showing the actual query that is input by the user, it shows the
truncated logical plan as the input. We should improve it to show the query
text as input by user.
Here are the sample outputs of the explain command.
{code:java}
EXPLAIN DESCRIBE WITH s AS (SELECT 'hello' as col1) SELECT * FROM s;
== Physical Plan ==
Execute DescribeQueryCommand
+- DescribeQueryCommand CTE [s]
{code}
{code:java}
EXPLAIN EXTENDED DESCRIBE SELECT * from s1 where c1 > 0;
== Physical Plan ==
Execute DescribeQueryCommand
+- DescribeQueryCommand 'Project [*]
{code}
