spark如何合并github

小编给大家分享一下spark如何合并github，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

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 ...[ERROR] [Error] resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala:298: value setRolledLogsIncludePattern is not a member of org.apache.hadoop.yarn.api.records.LogAggregationContext[ERROR] [Error] resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala:300: value setRolledLogsExcludePattern is not a member of org.apache.hadoop.yarn.api.records.LogAggregationContext[ERROR] [Error] resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala:551: not found: value isLocalUri[ERROR] [Error] resource-managers/yarn/src/main/scala/org/apache/spark/deploy/yarn/Client.scala:1367: not found: value isLocalUri[ERROR] four errors found

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
