> Properly explain the streaming queries
> --------------------------------------

> Key: SPARK-15443
> URL: https://issues.apache.org/jira/browse/SPARK-15443
> Project: Spark
> Issue Type: Sub-task
> Components: SQL, Streaming
> Affects Versions: 2.0.0
> Reporter: Saisai Shao
> Assignee: Shixiong Zhu
> Priority: Minor
> Fix For: 2.0.1, 2.1.0
>
>
> Currently when called `explain()` on streaming dataset, it will only get the
> parsed and analyzed logical plan, exceptions for optimized logical plan and
> physical plan, like below:
> {code}
> scala> res0.explain(true)
> == Parsed Logical Plan ==
> FileSource[file:///tmp/input]
> == Analyzed Logical Plan ==
> value: string
> FileSource[file:///tmp/input]
> == Optimized Logical Plan ==
> org.apache.spark.sql.AnalysisException: Queries with streaming sources must
> be executed with write.startStream();
> == Physical Plan ==
> org.apache.spark.sql.AnalysisException: Queries with streaming sources must
> be executed with write.startStream();
> {code}
> The reason is that structure streaming dynamically materialize the plan in
> the run-time.
> So here we should figure out a way to properly get the streaming plan.
