…ry page This issue is pretty similar to [SPARK-21907](https://issues.apache.org/jira/browse/SPARK-21907). "allocateArray" in [ShuffleInMemorySorter.reset](https://github.com/apache/spark/blob/9b8521e53e56a53b44c02366a99f8a8ee1307bbf/core/src/main/java/org/apache/spark/shuffle/sort/ShuffleInMemorySorter.java#L99) may trigger a spill and cause ShuffleInMemorySorter access the released `array`. Another task may get the same memory page from the pool. This will cause two tasks access the same memory page. When a task reads memory written by another task, many types of failures may happen. Here are some examples I have seen: - JVM crash. (This is easy to reproduce in a unit test as we fill newly allocated and deallocated memory with 0xa5 and 0x5a bytes which usually points to an invalid memory address) - java.lang.IllegalArgumentException: Comparison method violates its general contract! - java.lang.NullPointerException at org.apache.spark.memory.TaskMemoryManager.getPage(TaskMemoryManager.java:384) - java.lang.UnsupportedOperationException: Cannot grow BufferHolder by size -536870912 because the size after growing exceeds size limitation 2147483632 This PR resets states in `ShuffleInMemorySorter.reset` before calling `allocateArray` to fix the issue. The new unit test will make JVM crash without the fix. Closes apache#22062 from zsxwing/SPARK-25081. Authored-by: Shixiong Zhu <[email protected]> Signed-off-by: Shixiong Zhu <[email protected]>

…access released memory page (branch-2.2) ## What changes were proposed in this pull request? Backport #22062 to branch-2.2. Just two minor differences in the test: - branch-2.2 doesn't have `SparkOutOfMemoryError`. It's using `OutOfMemoryError` directly. - MockitoSugar is in a different package in old scalatest. ## How was this patch tested? Jenkins Closes #22072 from zsxwing/SPARK-25081-2.2.
