[SPARK-32105][SQL]Refactor current ScriptTransformationExec code by AngersZhuuuu · Pull Request #27983 · apache/spark

AngersZhuuuu · 2020-03-23T06:06:33Z

What changes were proposed in this pull request?

Renamed hive transform scrip class hive/execution/ScriptTransformationExec to hive/execution/HiveScriptTransformationExec (don't rename file)
Extract class BaseScriptTransformationExec about common code used across SparkScriptTransformationExec(next pr add this) and HiveScriptTransformationExec
Extract class BaseScriptTransformationWriterThread of writing data thread across SparkScriptTransformationWriterThread(added next for support transform in sql/core ) and HiveScriptTransformationWriterThread ,
HiveScriptTransformationWriterThread additionally supports Hive serde format
Rename current Script strategies in hive module to HiveScript, in next pr will add SparkScript strategies for support transform in sql/core.

Todo List;

Support transform in sql/core base on BaseScriptTransformationExec, which would run script operator in SQL mode (without Hive).
The output of script would be read as a string and column values are extracted by using a delimiter (default : tab character)
For Hive, by default only serde's must be used, and without hive we can run without serde
Cleanup past hacks that are observed (and people suggest / report)， such as
- Solve string value error about Date/Timestamp in ScriptTransform
- support use transform with aggregation
- support array/map as transform's input
Use code-gen projection to serialize rows to output stream()

Why are the changes needed?

Support run transform in SQL mode without hive

Does this PR introduce any user-facing change?

Yes

How was this patch tested?

Added UT

+ (3, "3", 3.0, BigDecimal(3.0), new Timestamp(3), Date.valueOf("2015-05-23"))
+ ).toDF("a", "b", "c", "d", "e", "f") // Note column d's data type is Decimal(38, 18)
+ df.createTempView("v")
+


Here add test case of Timestamp and DateType

@gatorsmile @tejasapatil @wangyum

I have restart implement ScriptTransform in sql/core now,

Rewrite origin pr in current code. Hope for your review and suggestion

Seems not need to create new jira? just delete follow-up?

@dongjoon-hyun
In latest test,

org.apache.spark.sql.execution.script.ScriptTransformationSuite.SPARK-14400 script transformation should fail for bad script command

Seem sometimes it won't catch the subprocess's exception.
I tried a lot of times, sometimes failed, sometimes success. May have problem about catch subproc's exception.
