LuciferYang opened a new pull request #31939:
URL: https://github.com/apache/spark/pull/31939
### What changes were proposed in this pull request?
SPARK-32160 add a config(`EXECUTOR_ALLOW_SPARK_CONTEXT`) to switch
allow/disallow to create `SparkContext` in executors and the default value of
the config is `false`
`ExternalAppendOnlyUnsafeRowArrayBenchmark` will fail when
`EXECUTOR_ALLOW_SPARK_CONTEXT` use the default value because the
`ExternalAppendOnlyUnsafeRowArrayBenchmark#withFakeTaskContext` method try to
create a `SparkContext` manually in Executor Side.
So the main change of this pr is set `EXECUTOR_ALLOW_SPARK_CONTEXT` to
`true` to ensure `ExternalAppendOnlyUnsafeRowArrayBenchmark` run successfully.
### Why are the changes needed?
Bug fix.
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Manual test：
```
bin/spark-submit --class
org.apache.spark.sql.execution.ExternalAppendOnlyUnsafeRowArrayBenchmark --jars
spark-core_2.12-3.2.0-SNAPSHOT-tests.jar
spark-sql_2.12-3.2.0-SNAPSHOT-tests.jar
```
**Before**
```
Exception in thread "main" java.lang.IllegalStateException: SparkContext
should only be created and accessed on the driver.
