### What changes were proposed in this pull request? To support formatted explain for AQE. ### Why are the changes needed? AQE does not support formatted explain yet. It's good to support it for better user experience, debugging, etc. Before: ``` == Physical Plan == AdaptiveSparkPlan (1) +- * HashAggregate (unknown) +- CustomShuffleReader (unknown) +- ShuffleQueryStage (unknown) +- Exchange (unknown) +- * HashAggregate (unknown) +- * Project (unknown) +- * BroadcastHashJoin Inner BuildRight (unknown) :- * LocalTableScan (unknown) +- BroadcastQueryStage (unknown) +- BroadcastExchange (unknown) +- LocalTableScan (unknown) (1) AdaptiveSparkPlan Output [4]: [k#7, count(v1)#32L, sum(v1)#33L, avg(v2)#34] Arguments: HashAggregate(keys=[k#7], functions=[count(1), sum(cast(v1#8 as bigint)), avg(cast(v2#19 as bigint))]), AdaptiveExecutionContext(org.apache.spark.sql.SparkSession104ab57b), [PlanAdaptiveSubqueries(Map())], false ``` After: ``` == Physical Plan == AdaptiveSparkPlan (14) +- * HashAggregate (13) +- CustomShuffleReader (12) +- ShuffleQueryStage (11) +- Exchange (10) +- * HashAggregate (9) +- * Project (8) +- * BroadcastHashJoin Inner BuildRight (7) :- * Project (2) : +- * LocalTableScan (1) +- BroadcastQueryStage (6) +- BroadcastExchange (5) +- * Project (4) +- * LocalTableScan (3) (1) LocalTableScan [codegen id : 2] Output [2]: [_1#x, _2#x] Arguments: [_1#x, _2#x] (2) Project [codegen id : 2] Output [2]: [_1#x AS k#x, _2#x AS v1#x] Input [2]: [_1#x, _2#x] (3) LocalTableScan [codegen id : 1] Output [2]: [_1#x, _2#x] Arguments: [_1#x, _2#x] (4) Project [codegen id : 1] Output [2]: [_1#x AS k#x, _2#x AS v2#x] Input [2]: [_1#x, _2#x] (5) BroadcastExchange Input [2]: [k#x, v2#x] Arguments: HashedRelationBroadcastMode(List(cast(input[0, int, false] as bigint))), [id=#x] (6) BroadcastQueryStage Output [2]: [k#x, v2#x] Arguments: 0 (7) BroadcastHashJoin [codegen id : 2] Left keys [1]: [k#x] Right keys [1]: [k#x] Join condition: None (8) Project [codegen id : 2] Output [3]: [k#x, v1#x, v2#x] Input [4]: [k#x, v1#x, k#x, v2#x] (9) HashAggregate [codegen id : 2] Input [3]: [k#x, v1#x, v2#x] Keys [1]: [k#x] Functions [3]: [partial_count(1), partial_sum(cast(v1#x as bigint)), partial_avg(cast(v2#x as bigint))] Aggregate Attributes [4]: [count#xL, sum#xL, sum#x, count#xL] Results [5]: [k#x, count#xL, sum#xL, sum#x, count#xL] (10) Exchange Input [5]: [k#x, count#xL, sum#xL, sum#x, count#xL] Arguments: hashpartitioning(k#x, 5), true, [id=#x] (11) ShuffleQueryStage Output [5]: [sum#xL, k#x, sum#x, count#xL, count#xL] Arguments: 1 (12) CustomShuffleReader Input [5]: [k#x, count#xL, sum#xL, sum#x, count#xL] Arguments: coalesced (13) HashAggregate [codegen id : 3] Input [5]: [k#x, count#xL, sum#xL, sum#x, count#xL] Keys [1]: [k#x] Functions [3]: [count(1), sum(cast(v1#x as bigint)), avg(cast(v2#x as bigint))] Aggregate Attributes [3]: [count(1)#xL, sum(cast(v1#x as bigint))#xL, avg(cast(v2#x as bigint))#x] Results [4]: [k#x, count(1)#xL AS count(v1)#xL, sum(cast(v1#x as bigint))#xL AS sum(v1)#xL, avg(cast(v2#x as bigint))#x AS avg(v2)#x] (14) AdaptiveSparkPlan Output [4]: [k#x, count(v1)#xL, sum(v1)#xL, avg(v2)#x] Arguments: isFinalPlan=true ``` ### Does this PR introduce any user-facing change? No, this should be new feature along with AQE in Spark 3.0. ### How was this patch tested? Added a query file: `explain-aqe.sql` and a unit test.

…or its output partitioning ### What changes were proposed in this pull request? Currently, the `BroadcastHashJoinExec`'s `outputPartitioning` only uses the streamed side's `outputPartitioning`. However, if the join type of `BroadcastHashJoinExec` is an inner-like join, the build side's info (the join keys) can be added to `BroadcastHashJoinExec`'s `outputPartitioning`. For example, ```Scala spark.conf.set("spark.sql.autoBroadcastJoinThreshold", "500") val t1 = (0 until 100).map(i => (i % 5, i % 13)).toDF("i1", "j1") val t2 = (0 until 100).map(i => (i % 5, i % 13)).toDF("i2", "j2") val t3 = (0 until 20).map(i => (i % 7, i % 11)).toDF("i3", "j3") val t4 = (0 until 100).map(i => (i % 5, i % 13)).toDF("i4", "j4") // join1 is a sort merge join. val join1 = t1.join(t2, t1("i1") === t2("i2")) // join2 is a broadcast join where t3 is broadcasted. val join2 = join1.join(t3, join1("i1") === t3("i3")) // Join on the column from the broadcasted side (i3). val join3 = join2.join(t4, join2("i3") === t4("i4")) join3.explain ``` You see that `Exchange hashpartitioning(i2#103, 200)` is introduced because there is no output partitioning info from the build side. ``` == Physical Plan == *(6) SortMergeJoin [i3#29], [i4#40], Inner :- *(4) Sort [i3#29 ASC NULLS FIRST], false, 0 : +- Exchange hashpartitioning(i3#29, 200), true, [id=#55] : +- *(3) BroadcastHashJoin [i1#7], [i3#29], Inner, BuildRight : :- *(3) SortMergeJoin [i1#7], [i2#18], Inner : : :- *(1) Sort [i1#7 ASC NULLS FIRST], false, 0 : : : +- Exchange hashpartitioning(i1#7, 200), true, [id=#28] : : : +- LocalTableScan [i1#7, j1#8] : : +- *(2) Sort [i2#18 ASC NULLS FIRST], false, 0 : : +- Exchange hashpartitioning(i2#18, 200), true, [id=#29] : : +- LocalTableScan [i2#18, j2#19] : +- BroadcastExchange HashedRelationBroadcastMode(List(cast(input[0, int, false] as bigint))), [id=#34] : +- LocalTableScan [i3#29, j3#30] +- *(5) Sort [i4#40 ASC NULLS FIRST], false, 0 +- Exchange hashpartitioning(i4#40, 200), true, [id=#39] +- LocalTableScan [i4#40, j4#41] ``` This PR proposes to introduce output partitioning for the build side for `BroadcastHashJoinExec` if the streamed side has a `HashPartitioning` or a collection of `HashPartitioning`s. There is a new internal config `spark.sql.execution.broadcastHashJoin.outputPartitioningExpandLimit`, which can limit the number of partitioning a `HashPartitioning` can expand to. It can be set to "0" to disable this feature. ### Why are the changes needed? To remove unnecessary shuffle. ### Does this PR introduce _any_ user-facing change? Yes, now the shuffle in the above example can be eliminated: ``` == Physical Plan == *(5) SortMergeJoin [i3#108], [i4#119], Inner :- *(3) Sort [i3#108 ASC NULLS FIRST], false, 0 : +- *(3) BroadcastHashJoin [i1#86], [i3#108], Inner, BuildRight : :- *(3) SortMergeJoin [i1#86], [i2#97], Inner : : :- *(1) Sort [i1#86 ASC NULLS FIRST], false, 0 : : : +- Exchange hashpartitioning(i1#86, 200), true, [id=#120] : : : +- LocalTableScan [i1#86, j1#87] : : +- *(2) Sort [i2#97 ASC NULLS FIRST], false, 0 : : +- Exchange hashpartitioning(i2#97, 200), true, [id=#121] : : +- LocalTableScan [i2#97, j2#98] : +- BroadcastExchange HashedRelationBroadcastMode(List(cast(input[0, int, false] as bigint))), [id=#126] : +- LocalTableScan [i3#108, j3#109] +- *(4) Sort [i4#119 ASC NULLS FIRST], false, 0 +- Exchange hashpartitioning(i4#119, 200), true, [id=#130] +- LocalTableScan [i4#119, j4#120] ``` ### How was this patch tested? Added new tests. Closes apache#28676 from imback82/broadcast_join_output. Authored-by: Terry Kim <[email protected]> Signed-off-by: Wenchen Fan <[email protected]>

…on to make Java 17 compatible with Java 8 ### What changes were proposed in this pull request? The `date_format` function with `B` format has different behavior when use Java 8 and Java 17, `select date_format('2018-11-17 13:33:33.333', 'B')` in `datetime-formatting-invalid.sql` can prove this. The case result with Java 8 is ``` -- !query select date_format('2018-11-17 13:33:33.333', 'B') -- !query schema struct<> -- !query output java.lang.IllegalArgumentException Unknown pattern letter: B ``` and the case result with Java 17 is ``` - datetime-formatting-invalid.sql *** FAILED *** datetime-formatting-invalid.sql Expected "struct<[]>", but got "struct<[date_format(2018-11-17 13:33:33.333, B):string]>" Schema did not match for query Kyligence#34 select date_format('2018-11-17 13:33:33.333', 'B'): -- !query select date_format('2018-11-17 13:33:33.333', 'B') -- !query schema struct<date_format(2018-11-17 13:33:33.333, B):string> -- !query output in the afternoon (SQLQueryTestSuite.scala:469) ``` We found that this is due to the new support of format `B` in Java 17 ``` 'B' is used to represent Pattern letters to output a day period in Java 17 * Pattern Count Equivalent builder methods * ------- ----- -------------------------- * B 1 appendDayPeriodText(TextStyle.SHORT) * BBBB 4 appendDayPeriodText(TextStyle.FULL) * BBBBB 5 appendDayPeriodText(TextStyle.NARROW) ``` And through [ http://spark.apache.org/docs/latest/sql-ref-datetime-pattern.html]( http://spark.apache.org/docs/latest/sql-ref-datetime-pattern.html) , we can confirm that format `B` is not documented/supported for `date_format` function currently. So the main change of this pr is manual disabled format `B` of `date_format` function in `DateTimeFormatterHelper` to make Java 17 compatible with Java 8. ### Why are the changes needed? Ensure that Java 17 and Java 8 have the same behavior. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? - Pass the Jenkins or GitHub Action - Manual test `SQLQueryTestSuite` with JDK 17 **Before** ``` - datetime-formatting-invalid.sql *** FAILED *** datetime-formatting-invalid.sql Expected "struct<[]>", but got "struct<[date_format(2018-11-17 13:33:33.333, B):string]>" Schema did not match for query Kyligence#34 select date_format('2018-11-17 13:33:33.333', 'B'): -- !query select date_format('2018-11-17 13:33:33.333', 'B') -- !query schema struct<date_format(2018-11-17 13:33:33.333, B):string> -- !query output in the afternoon (SQLQueryTestSuite.scala:469) ``` **After** The test `select date_format('2018-11-17 13:33:33.333', 'B')` in `datetime-formatting-invalid.sql` passed Closes apache#34237 from LuciferYang/SPARK-36970.
