             Summary: Add modified configs for SQL execution in UI
                 Key: SPARK-34735
                 URL: https://issues.apache.org/jira/browse/SPARK-34735
             Project: Spark
          Issue Type: New Feature
          Components: SQL
    Affects Versions: 3.2.0
            Reporter: ulysses you


For SQL user, it's very common to add some config to optimize sql. Within a 
script, it would look like this
{code:java}
set k1=v1;
set k2=v2;
set ...

INSERT INTO TABLE t1
SELECT ...

{code}
 
 It's hard to find the configs used by sql without the raw sql string. Current 
UI provide a `Environment` tab that we can only get some global initial config, 
however it's not enough.

Some use case:
 * Jar based job, we might set config many times due to many sql execution.
 * SQL server e.g. (SparkThriftServer), we might execute thousands scripts 
every day with different session.

We expect a feature that can list the modified configs which could affect the 
sql execution.
