Spark低版本适配Celeborn

Spark-3.5版本以下使用Celeborn时，无法使用动态资源，对于低版本的Spark，Celeborn提供了patch。各版本patch如下

https://github.com/apache/incubator-celeborn/tree/main/assets/spark-patch

下载patch，这里下载spark-3版本，将Celeborn_Dynamic_Allocation_spark3_3.patch放至spark-3.3.1源码目录下，和core同一层级,执行如下命令代码合并

bash 复制代码

patch -p1 < Celeborn_Dynamic_Allocation_spark3_3.patch

重新编译spark源码，并生成spark tgz包

bash 复制代码

./dev/make-distribution.sh --tgz --name custom-spark -Phadoop-3.2 -Dhadoop.version=3.2.1 \
 -Phive-3.2.1 -Phive-thriftserver -Pyarn -DskipTests

提交任务

bash 复制代码
