jerqi opened a new pull request #34589:
URL: https://github.com/apache/spark/pull/34589
### What changes were proposed in this pull request?
Add `throws IOException` to `consumeFullOuterJoinRow` in ShuffledHashJoinExec
### Why are the changes needed?
If we don't have this patch, when the dataframes that have aggregate and
join at the same time use `wholeStageCodegen`, the dataframes will throw a
`CompileException`.
For example:
```scala
val df1 = spark.range(5).select($"id".as("k1"))
val df2 = spark.range(10).select($"id".as("k2"))
df1.join(df2.hint("SHUFFLE_HASH"), $"k1" === $"k2", "full_outer").count()
```
this query will throw Exception is as follows:
```
