Jihoon Son updated SPARK-52520:
-------------------------------
Description:
A deadlock was found while running a query, which got stuck while scheduling
next stages to run. Per stack traces, I believe this is what happened. Note
that I used the Spark-RAPIDS plugin.
* Thread A (Thread-5 in the stack traces below) acquired a lock on
ExplainUtils while running AdaptiveSparkPlanExec. With the lock acquired, it
tried to materialize all subqueries in the plan. It was waiting to lock
GpuFileSourceScanExec.
* Thread B (gpu-broadcast-exchange-127 in the below) acquired a lock on
GpuFileSourceScanExec.selectedPartitions, which is a lazy val. While evaluating
the lazy val, it tried to update delta log, which triggered evaluating a data
frame (because of delta). Evaluating a data frame required to explain the query
plan which required to lock ExplainUtils.
Even though I am seeing this issue with the Spark-RAPIDS plugin, I believe that
Apache Spark has the same issue as the function call hierarchy is almost
identical. The FileSourceScanExec class in Apache Spark also has the
[selectedPartitions lazy
val|https://github.com/apache/spark/blob/v3.4.3/sql/core/src/main/scala/org/apache/spark/sql/execution/DataSourceScanExec.scala#L251-L262],
which is computed in the same way as in the [Spark-RAPIDS
plugin|https://github.com/NVIDIA/spark-rapids/blob/v25.04.0/sql-plugin/src/main/scala/org/apache/spark/sql/rapids/GpuFileSourceScanExec.scala#L125-L136].
I noticed that this problem doesn't exist in Spark 3.5.x as the synchronization
on ExplainUtils were removed in
https://issues.apache.org/jira/browse/SPARK-48610. We should consider
backporting this fix to 3.4 branch as well.
Here are more details of the deadlock.
Found one Java-level deadlock:

> Deadlock in the executor with delta input and AQE on
> ----------------------------------------------------
>
> Key: SPARK-52520
> URL: https://issues.apache.org/jira/browse/SPARK-52520
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 3.4.3, 3.4.4
> Reporter: Jihoon Son
> Priority: Major
>
> A deadlock was found while running a query, which got stuck while scheduling
> next stages to run. Per stack traces, I believe this is what happened. Note
> that I used the Spark-RAPIDS plugin.
> * Thread A (Thread-5 in the stack traces below) acquired a lock on
> ExplainUtils while running AdaptiveSparkPlanExec. With the lock acquired, it
> tried to materialize all subqueries in the plan. It was waiting to lock
> GpuFileSourceScanExec.
> * Thread B (gpu-broadcast-exchange-127 in the below) acquired a lock on
> GpuFileSourceScanExec.selectedPartitions, which is a lazy val. While
> evaluating the lazy val, it tried to update delta log, which triggered
> evaluating a data frame (because of delta). Evaluating a data frame required
> to explain the query plan which required to lock ExplainUtils.
> Even though I am seeing this issue with the Spark-RAPIDS plugin, I believe
> that Apache Spark has the same issue as the function call hierarchy is almost
> identical. The FileSourceScanExec class in Apache Spark also has the
> [selectedPartitions lazy
> val|https://github.com/apache/spark/blob/v3.4.3/sql/core/src/main/scala/org/apache/spark/sql/execution/DataSourceScanExec.scala#L251-L262],
> which is computed in the same way as in the [Spark-RAPIDS
> plugin|https://github.com/NVIDIA/spark-rapids/blob/v25.04.0/sql-plugin/src/main/scala/org/apache/spark/sql/rapids/GpuFileSourceScanExec.scala#L125-L136].
>
> I noticed that this problem doesn't exist in Spark 3.5.x as the
> synchronization on ExplainUtils were removed in
> https://issues.apache.org/jira/browse/SPARK-48610. We should consider
> backporting this fix to 3.4 branch as well.
> Here are more details of the deadlock.
