[B]Spark版本适配改造（二）1.0.7+

# 第二步：重构 `do-component-build` 构建脚本

该脚本位于：

📁 bigtop-packages/src/common/spark/do-component-build

它是 Spark RPM 构建链中的关键步骤，控制了源码构建、分发包生成、Maven 安装等过程。

# be run after Spark has already been packaged.

# 📌 修改了哪些内容？

改动点汇总

将 BUILD_OPTS 从字符串拼接改为数组声明；
动态判断 SPARK_VERSION 来适配 Hadoop profile；
支持外部 SPARK_BUILD_OPTS 参数传入；
增加空参数清洗逻辑；
拆分出独立的 mvn install 流程，并全量添加 skip 相关参数。

# 🧩 修改的原因

原因说明

原始脚本在 Spark 3.5 下构建失败，因 -Phadoop-3.2 不兼容；
$SPARK_BUILD_OPTS 若为空，拼接会产生 ' ' 参数，导致构建失败；
构建阶段和 install 阶段参数不统一，影响产物准确性；
无法复用构建脚本做版本切换。

# 🔍 修改前后区别

维度	修改前	修改后
参数结构	字符串拼接	数组处理，逻辑清晰
Hadoop Profile	写死为 `-Phadoop-3.2`	根据版本自动切换
外部变量支持	直接拼接，易错	支持解析合并数组
参数污染处理	无	加入空值过滤机制
执行清晰度	make-distribution + install 混杂	明确拆分构建与 install 阶段
