算法库更新版本后，可以按照以下流程进行版本升级。

按照获取代码的说明获取最新的软件包。

以大数据组件的授权用户登录服务器，将原来客户端的“/home/test/boostkit/lib/”目录下的算法库软件包，替换成最新版本。

rm -f /home/test/boostkit/lib/boostkit-*
cp /opt/Spark-graph-algo-lib-1.3.0-spark2.3.2/graph-accelerator/target/boostkit-graph-acc_2.11-1.3.0-spark2.3.2.jar /home/test/boostkit/lib
cp /opt/Spark-graph-algo-lib-1.3.0-spark2.3.2/graph-accelerator/target/boostkit-graph-core_2.11-1.3.0-spark2.3.2.jar /home/test/boostkit/lib
cp /opt/boostkit-graph-kernel-2.11-1.3.0-spark2.3.2-aarch64.jar /home/test/boostkit/lib

将提交任务shell脚本中算法库软件包名替换成最新版本的包名，使用yarn-client模式启动Spark作业，替换后的shell脚本示例如下。

#!/bin/bash

spark-submit \
--class com.bigdata.graph.WCEMain \
--master yarn \
--deploy-mode client \
--driver-cores 36 \
--driver-memory 50g \
--jars "lib/fastutil-8.3.1.jar,lib/boostkit-graph-acc_2.11-1.3.0-spark2.3.2.jar,lib/boostkit-graph-kernel-2.11-1.3.0-spark2.3.2-aarch64.jar,lib/boostkit-graph-core_2.11-1.3.0-spark2.3.2.jar" \
--driver-class-path "lib/graph-test.jar:lib/fastutil-8.3.1.jar:lib/snakeyaml-1.17.jar:lib/boostkit-graph-acc_2.11-1.3.0-spark2.3.2.jar:lib/boostkit-graph-kernel-2.11-1.3.0-spark2.3.2-aarch64.jar:lib/boostkit-graph-core_2.11-1.3.0-spark2.3.2.jar" \
--conf "spark.executor.extraClassPath=fastutil-8.3.1.jar:boostkit-graph-acc_2.11-1.3.0-spark2.3.2.jar:boostkit-graph-kernel-2.11-1.3.0-spark2.3.2-aarch64.jar:boostkit-graph-core_2.11-1.3.0-spark2.3.2.jar" \
./graph-test.jar

将提交任务shell脚本中算法库软件包名替换成最新版本的包名，使用yarn-cluster模式启动Spark作业，替换后的shell脚本示例如下。

#!/bin/bash

spark-submit \
--class com.bigdata.graph.WCEMain \
--master yarn \
--deploy-mode cluster \
--driver-cores 36 \
--driver-memory 50g \
--jars "lib/fastutil-8.3.1.jar,lib/boostkit-graph-acc_2.11-1.3.0-spark2.3.2.jar,lib/boostkit-graph-kernel-2.11-1.3.0-spark2.3.2-aarch64.jar,lib/boostkit-graph-core_2.11-1.3.0-spark2.3.2.jar" \
--driver-class-path "graph-test.jar:fastutil-8.3.1.jar:snakeyaml-1.17.jar:boostkit-graph-acc_2.11-1.3.0-spark2.3.2.jar:boostkit-graph-kernel-2.11-1.3.0-spark2.3.2-aarch64.jar:boostkit-graph-core_2.11-1.3.0-spark2.3.2.jar" \
--conf "spark.yarn.cluster.driver.extraClassPath=graph-test.jar:snakeyaml-1.17.jar:boostkit-graph-kernel-2.11-1.3.0-spark2.3.2-aarch64.jar:boostkit-graph-acc_2.11-1.3.0-spark2.3.2.jar:boostkit-graph-core_2.11-1.3.0-spark2.3.2.jar" \
--conf "spark.executor.extraClassPath=fastutil-8.3.1.jar:boostkit-graph-acc_2.11-1.3.0-spark2.3.2.jar:boostkit-graph-kernel-2.11-1.3.0-spark2.3.2-aarch64.jar:boostkit-graph-core_2.11-1.3.0-spark2.3.2.jar" \
./graph-test.jar 

脚本中的语句含义如表2所示。
