### Support Spark Dynamic Allocation
To support spark dynamic allocation with Uniffle, spark code should be updated.
-There are 2 patches for spark-2.4.6 and spark-3.1.2 in spark-patches folder
for reference.
+There are 7 patches for spark (2.3.4/2.4.6/3.0.1/3.1.2/3.2.1/3.3.1/3.4.1) in
patch/spark folder for reference.
After apply the patch and rebuild spark, add following configuration in spark
conf to enable dynamic allocation:
```
spark.shuffle.service.enabled false
spark.dynamicAllocation.enabled true
```
+For spark3.5 or above just add one more configuration:
+ ```
+ spark.shuffle.sort.io.plugin.class org.apache.spark.shuffle.RssShuffleDataIo
+ ```
