Saisai Shao created SPARK-15443: ----------------------------------- Summary: Properly explain the streaming queries Key: SPARK-15443 URL: https://issues.apache.org/jira/browse/SPARK-15443 Project: Spark Issue Type: Bug Components: SQL, Streaming Affects Versions: 2.0.0 Reporter: Saisai Shao Priority: Minor
Currently when called `explain()` on streaming dataset, it will only get the parsed logical plan and 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
