我是靠谱客的博主 鳗鱼向日葵,最近开发中收集的这篇文章主要介绍window使用spark连接HDP-3.1.5.0时报Unrecognized Hadoop major version number: 3.1.1问题,觉得挺不错的,现在分享给大家,希望可以做个参考。
概述
当使用idea使用saprk连接hive时,报以下错误:Unrecognized Hadoop major version number: 3.1.1
pom依赖如下:

原因:hdp-3.1.5集成了hadoop3.1和spark2.3,当我idea使用2.3的spark时,不认识3.1的hadoop,查看源码发现:
spark2.3的源码里,没有对应hadoop3.x的版本,继续深究源码发现是以common-version-info.properties文件里包含了版本信息
解决办法:
在classpath目录下添加common-version-info.properties文件,内容指定版本
(虽然我Pom依赖里Hadoop是3.x,但是不影响),内容如下:
最后代码spark代码如下:
package org.yw
import java.sql.DriverManager
import java.util.Properties
import org.apache.spark.sql.SparkSession
import org.yw.db.PhoenixDB
object SparkTest {
def main(args: Array[String]): Unit = {
var master = "local"
var sql = "select * from person"
val spark = SparkSession
.builder()
.appName("test hive")
.master(master)
// 指定hive的metastore的端口 默认为9083 在hive-site.xml中查看
.config("hive.metastore.uris", "thrift://bigdata03:9083")
//指定hive的warehouse目录
.config("spark.sql.warehouse.dir", "hdfs://ns//warehouse/tablespace/external/hive")
.enableHiveSupport()
.getOrCreate()
spark.sql(sql).show()
}
}
输出如下
