Minor Description
For SQL user, it's very common to add some config to optimize sql. Within a script, it would look like this
set k1=v1; set k2=v2; set ... INSERT INTO TABLE t1 SELECT ...
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.
