…parkR ### What changes were proposed in this pull request? This PR proposes to set the minimum Arrow version as 1.0.0 to minimise the maintenance overhead and keep the minimal version up to date. Other required changes to support 1.0.0 were already made in SPARK-32451. ### Why are the changes needed? R side, people rather aggressively encourage people to use the latest version, and SparkR vectorization is very experimental that was added from Spark 3.0. Also, we're technically not testing old Arrow versions in SparkR for now. ### Does this PR introduce _any_ user-facing change? Yes, users wouldn't be able to use SparkR with old Arrow. ### How was this patch tested? GitHub Actions and AppVeyor are already testing them. Closes apache#29253 from HyukjinKwon/SPARK-32452.

…ingBuilder` ### What changes were proposed in this pull request? This PR aims to improve `toString` by `JEP-280` instead of `ToStringBuilder`. In addition, `Scalastyle` and `Checkstyle` rules are added to prevent a future regression. ### Why are the changes needed? Since Java 9, `String Concatenation` has been handled better by default. | ID | DESCRIPTION | | - | - | | JEP-280 | [Indify String Concatenation](https://openjdk.org/jeps/280) | For example, this PR improves `OpenBlocks` like the following. Both Java source code and byte code are simplified a lot by utilizing JEP-280 properly. **CODE CHANGE** ```java - return new ToStringBuilder(this, ToStringStyle.SHORT_PREFIX_STYLE) - .append("appId", appId) - .append("execId", execId) - .append("blockIds", Arrays.toString(blockIds)) - .toString(); + return "OpenBlocks[appId=" + appId + ",execId=" + execId + ",blockIds=" + + Arrays.toString(blockIds) + "]"; ``` **BEFORE** ``` public java.lang.String toString(); Code: 0: new #39 // class org/apache/commons/lang3/builder/ToStringBuilder 3: dup 4: aload_0 5: getstatic #41 // Field org/apache/commons/lang3/builder/ToStringStyle.SHORT_PREFIX_STYLE:Lorg/apache/commons/lang3/builder/ToStringStyle; 8: invokespecial #47 // Method org/apache/commons/lang3/builder/ToStringBuilder."<init>":(Ljava/lang/Object;Lorg/apache/commons/lang3/builder/ToStringStyle;)V 11: ldc #50 // String appId 13: aload_0 14: getfield #7 // Field appId:Ljava/lang/String; 17: invokevirtual #51 // Method org/apache/commons/lang3/builder/ToStringBuilder.append:(Ljava/lang/String;Ljava/lang/Object;)Lorg/apache/commons/lang3/builder/ToStringBuilder; 20: ldc apache#55 // String execId 22: aload_0 23: getfield #13 // Field execId:Ljava/lang/String; 26: invokevirtual #51 // Method org/apache/commons/lang3/builder/ToStringBuilder.append:(Ljava/lang/String;Ljava/lang/Object;)Lorg/apache/commons/lang3/builder/ToStringBuilder; 29: ldc apache#56 // String blockIds 31: aload_0 32: getfield #16 // Field blockIds:[Ljava/lang/String; 35: invokestatic apache#57 // Method java/util/Arrays.toString:([Ljava/lang/Object;)Ljava/lang/String; 38: invokevirtual #51 // Method org/apache/commons/lang3/builder/ToStringBuilder.append:(Ljava/lang/String;Ljava/lang/Object;)Lorg/apache/commons/lang3/builder/ToStringBuilder; 41: invokevirtual apache#61 // Method org/apache/commons/lang3/builder/ToStringBuilder.toString:()Ljava/lang/String; 44: areturn ``` **AFTER** ``` public java.lang.String toString(); Code: 0: aload_0 1: getfield #7 // Field appId:Ljava/lang/String; 4: aload_0 5: getfield #13 // Field execId:Ljava/lang/String; 8: aload_0 9: getfield #16 // Field blockIds:[Ljava/lang/String; 12: invokestatic #39 // Method java/util/Arrays.toString:([Ljava/lang/Object;)Ljava/lang/String; 15: invokedynamic #43, 0 // InvokeDynamic #0:makeConcatWithConstants:(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;)Ljava/lang/String; 20: areturn ``` ### Does this PR introduce _any_ user-facing change? No. This is an `toString` implementation improvement. ### How was this patch tested? Pass the CIs. ### Was this patch authored or co-authored using generative AI tooling? No. Closes apache#51572 from dongjoon-hyun/SPARK-52880. Authored-by: Dongjoon Hyun <dongjoon@apache.org> Signed-off-by: Dongjoon Hyun <dongjoon@apache.org>

…onicalized expressions
### What changes were proposed in this pull request?
Make PullOutNonDeterministic use canonicalized expressions to dedup group and aggregate expressions. This affects pyspark udfs in particular. Example:
```
from pyspark.sql.functions import col, avg, udf
pythonUDF = udf(lambda x: x).asNondeterministic()
spark.range(10)\
.selectExpr("id", "id % 3 as value")\
.groupBy(pythonUDF(col("value")))\
.agg(avg("id"), pythonUDF(col("value")))\
.explain(extended=True)
```
Currently results in a plan like this:
```
Aggregate [_nondeterministic#15](#15), [_nondeterministic#15 AS dummyNondeterministicUDF(value)#12, avg(id#0L) AS avg(id)#13, dummyNondeterministicUDF(value#6L)#8 AS dummyNondeterministicUDF(value)#14](#15%20AS%20dummyNondeterministicUDF(value)#12,%20avg(id#0L)%20AS%20avg(id)#13,%20dummyNondeterministicUDF(value#6L)#8%20AS%20dummyNondeterministicUDF(value)#14)
+- Project [id#0L, value#6L, dummyNondeterministicUDF(value#6L)#7 AS _nondeterministic#15](#0L,%20value#6L,%20dummyNondeterministicUDF(value#6L)#7%20AS%20_nondeterministic#15)
+- Project [id#0L, (id#0L % cast(3 as bigint)) AS value#6L](#0L,%20(id#0L%20%%20cast(3%20as%20bigint))%20AS%20value#6L)
+- Range (0, 10, step=1, splits=Some(2))
```
and then it throws:
```
[[MISSING_AGGREGATION] The non-aggregating expression "value" is based on columns which are not participating in the GROUP BY clause. Add the columns or the expression to the GROUP BY, aggregate the expression, or use "any_value(value)" if you do not care which of the values within a group is returned. SQLSTATE: 42803
```
- how canonicalized fixes this:
- nondeterministic PythonUDF expressions always have distinct resultIds per udf
- The fix is to canonicalize the expressions when matching. Canonicalized means that we're setting the resultIds to -1, allowing us to dedup the PythonUDF expressions.
- for deterministic UDFs, this rule does not apply and "Post Analysis" batch extracts and deduplicates the expressions, as expected
### Why are the changes needed?
- the output of the query with the fix applied still makes sense - the nondeterministic UDF is invoked only once, in the project.
### Does this PR introduce _any_ user-facing change?
Yes, it's additive, it enables queries to run that previously threw errors.
### How was this patch tested?
- added unit test
### Was this patch authored or co-authored using generative AI tooling?
No
