-----------------------------------
Thanks for reply, I posted the failure message above in more detail. please
check it.
> Fail in fetch shuffle blocks in batch when i/o encryption is enabled.
> ---------------------------------------------------------------------
>
> Key: SPARK-34790
> URL: https://issues.apache.org/jira/browse/SPARK-34790
> Project: Spark
> Issue Type: Sub-task
> Components: Spark Core
> Affects Versions: 3.1.1
> Reporter: hezuojiao
> Priority: Major
>
> When set spark.io.encryption.enabled=true, lots of test cases in
> AdaptiveQueryExecSuite will be failed. Fetching shuffle blocks in batch is
> incompatible with io encryption.
> For example:
> After set spark.io.encryption.enabled=true, run the following test suite
> which in AdaptiveQueryExecSuite:
>
> {code:java}
> test("SPARK-33494: Do not use local shuffle reader for repartition") {
> withSQLConf(SQLConf.ADAPTIVE_EXECUTION_ENABLED.key -> "true") {
> val df = spark.table("testData").repartition('key)
> df.collect()
> // local shuffle reader breaks partitioning and shouldn't be used for
> repartition operation
> // which is specified by users.
> checkNumLocalShuffleReaders(df.queryExecution.executedPlan,
> numShufflesWithoutLocalReader = 1)
> }
> }
> {code}
