             Summary: Incomplete Graphical SQL Plan in Spark application UI's SQL tab for SaveIntoDataSourceCommand
                 Key: SPARK-30064
                 URL: https://issues.apache.org/jira/browse/SPARK-30064
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.4.4, 2.3.4, 3.0.0, 3.1.0
            Reporter: Reza Safi


For reproduction consider the following for jdbc datasource:
{noformat}
spark-shell --master yarn-client --jars /*/mysql-connector-java.jar 
import java.util.Properties 
val connectionProperties = new Properties() 
connectionProperties.put("user", "***") 
connectionProperties.put("driver", "com.mysql.jdbc.Driver") 
val jdbc_url ="jdbc:mysql://****"
Seq(1 -> "a").toDF("i", "j").write.mode("append").jdbc(jdbc_url,"test.test3",connectionProperties)
{noformat}

Then check the web UI's SQL tab and select the query and look at the plan. You will see a one node tree for the plan which just says "Execute SaveIntoDataSourceCommand".
It seems that the bug was first fixed in SPARK-20213(PR#18064), but that fix was partially reverted in SPARK-22252(PR#19474).
It seems that the fix should be to make SaveIntoDataSourceCommand to have an actual child for the run method, but that requires changes to other places.
