最近在做内部spark版本升级的工作,涉及到github 上合并pr的工作,具体的是spark 2.x升级到spark 3.0.1时兼容hdfs cdh-2.6.0-5.13.1,报编译错误
[INFO] Compiling 25 Scala sources to /Users/libinsong/Documents/codes/tongdun/spark-3.0/resource-managers/yarn/target/scala-2.12/classes ...

具体的解决方法github spark pr 已经给出了解决方法,修改相应的代码就行,但是仅仅是修改的话,我们可以选择一种更加优雅的方式(以git cherry-pick方式),
现在简单的分享一下:
直接找到setRolledLogsIncludePattern一行,
sparkConf.get(ROLLED_LOG_INCLUDE_PATTERN).foreach { includePattern => try { val logAggregationContext = Records.newRecord(classOf[LogAggregationContext]) logAggregationContext.setRolledLogsIncludePattern(includePattern) sparkConf.get(ROLLED_LOG_EXCLUDE_PATTERN).foreach { excludePattern => logAggregationContext.setRolledLogsExcludePattern(excludePattern) } appContext.setLogAggregationContext(logAggregationContext) } catch { case NonFatal(e) => logWarning(s"Ignoring ${ROLLED_LOG_INCLUDE_PATTERN.key} because the version of YARN " + "does not support it", e) } } appContext.setUnmanagedAM(isClientUnmanagedAMEnabled) sparkConf.get(APPLICATION_PRIORITY).foreach { appPriority => appContext.setPriority(Priority.newInstance(appPriority)) } appContext }
发现master上的代码并不是我们想要的,这个时候我们就可以使用git blame,在github上为
这样我们就能发现该代码有多次修改,找到对应[SPARK-19545][YARN] Fix compile issue for Spark on Yarn when building… 点击进去
找到对应的commitId
执行命令 git cherry-pick 8e8afb3a3468aa743d13e23e10e77e94b772b2ed 就能把该commit 追加到自己的工作目录下
这样既能不需要手动修改代码,也能很好的保存了原始的commit的信息,以便追踪
