编译Spark3.x

1.修改 D:\source\spark-3.0.0\dev\make-distribution.sh

将133行-151行注释，按如下方式修改

VERSION=3.0.0
SCALA_VERSION=2.12
SPARK_HADOOP_VERSION=2.6.0-cdh5.16.2
SPARK_HIVE=1
#VERSION=$("$MVN" help:evaluate -Dexpression=project.version $@ 2>/dev/null\
#    | grep -v "INFO"\
#    | grep -v "WARNING"\
#    | tail -n 1)
#SCALA_VERSION=$("$MVN" help:evaluate -Dexpression=scala.binary.version $@ 2>/dev/null\
#    | grep -v "INFO"\
#    | grep -v "WARNING"\
#    | tail -n 1)
#SPARK_HADOOP_VERSION=$("$MVN" help:evaluate -Dexpression=hadoop.version $@ 2>/dev/null\
#    | grep -v "INFO"\
#    | grep -v "WARNING"\
#    | tail -n 1)
#SPARK_HIVE=$("$MVN" help:evaluate -Dexpression=project.activeProfiles -pl sql/hive $@ 2>/dev/null\
#    | grep -v "INFO"\
#    | grep -v "WARNING"\
#    | fgrep --count "<id>hive</id>";\
#    # Reset exit status to 0, otherwise the script stops here if the last grep finds nothing\
#    # because we use "set -o pipefail"
#    echo -n)

2.修改D:\source\spark-3.0.0\pom.xml

修改profile ，将其默认的版本改成自己的hadoop版本，scala版本

3.在Git中开始编译

1    ./dev/change-scala-version.sh 2.12  
2    ./dev/make-distribution.sh --name 2.6.0-cdh5.16.2 --tgz -Phive -Phive-thriftserver -Pyarn -Phadoop-2.6 -Dhadoop.version=2.6.0-cdh5.16.2 -Dscala.version=2.12.10

如果你的hadoop版本低于2.6.4此时编译到yarn环节会报错：

修改源码：

D:\source\spark-3.0.0\resource-managers\yarn\src\main\scala\org\apache\spark\deploy\yarn\Client.scala

修改295行。由于这两个方法是hadoop2.6.4添加的，如果你的hadoop版本低于2.6.4，那么编译就会报错。

按如下方式修改即可解决问题

//    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
//  }

    sparkConf.get(ROLLED_LOG_INCLUDE_PATTERN).foreach { includePattern =>
      try {
        val logAggregationContext = Records.newRecord(classOf[LogAggregationContext])

        // These two methods were added in Hadoop 2.6.4, so we still need to use reflection to
        // avoid compile error when building against Hadoop 2.6.0 ~ 2.6.3.
        val setRolledLogsIncludePatternMethod =
          logAggregationContext.getClass.getMethod("setRolledLogsIncludePattern", classOf[String])
        setRolledLogsIncludePatternMethod.invoke(logAggregationContext, includePattern)

        sparkConf.get(ROLLED_LOG_EXCLUDE_PATTERN).foreach { excludePattern =>
          val setRolledLogsExcludePatternMethod =
            logAggregationContext.getClass.getMethod("setRolledLogsExcludePattern", classOf[String])
          setRolledLogsExcludePatternMethod.invoke(logAggregationContext, 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
  }

Spark3.X------Spark-Sql读取hive数据

启动Spark-Sql 必须使用--driver-class-path 把mysql的驱动传入，--jars可能不起作用

问题1

报错信息以及原因：

Spark3.x 指定的Hive版本是2.X 我们使用的Hive版本是1.1.0，Spark3.0调用的方法是ThriftHiveMetastore$Client.get_table_req ，但是Hive1.1.0不支持

Error in query: org.apache.hadoop.hive.ql.metadata.HiveException: Unable to fetch table hive_metadata_test. Invalid method name: 'get_table_req';

启动Spark-Sql的时候使用--conf将以下两个参数传入，或者修改spark3.x/conf/spark-defaults.conf 把下面两个配置项加入进去。

spark.sql.hive.metastore.version=1.1.0 #Hive版本
spark.sql.hive.metastore.jars=/home/badass/app/hive/lib/* #当前使用的Hive的lib目录

问题2

解决[问题1]，启动Spark-Sql，还会出现以下问题。

报错信息以及原因：

由于问题1中的Hive版本兼容问题，我们使用spark.sql.hive.metastore.jars来修改Spark加载访问Hive Metastore的类。

Spark允许用户设置spark.sql.hive.metastore.jars以指定jar来访问Hive Metastore。这些jar由独立的类加载器加载。因为我们还与独立的类加载器共享Hadoop类，所以用户不需要将Hadoop jar添加到中spark.sql.hive.metastore.jars，这意味着当我们使用独立的类加载器时，在这种情况下hadoop-common jar不可用。如果在切换到独立的类加载器之前未初始化Hadoop VersionInfo，并尝试使用隔离的类加载器（当前线程上下文类加载器）对其进行初始化，它将失败并报告，这将Unknown导致Hive引发以下异常。

解决办法：

https://github.com/apache/spark/pull/29059 这里的解决方法是修改类的加载方式，按照patch修改源码重新编译。

上面的方法比较麻烦，因为获取VersionInfo 需要hadoop-common jar，并且由于spark.sql.hive.metastore.jars 的配置导致无法获取VersionInfo，所以最便捷的解决方法就是将hadoop/share/hadoop/common/hadoop-common-2.6.0-cdh5.16.2.jar 这个jar包拷贝到hive的lib下。最后启动Spark-Sql完成，并使用Spark-Sql读取到了Hive的数据。
