在Win10中,在IntelliJ中,此路径(“C:/hive/Orders_[0-9]*.csv”)在作为独立的java spark作业运行时工作良好。但不作为Sping Boot spark作业工作。似乎Sping Boot 没有检测到本机文件夹。不知道如何解决这个问题。
Dataset<Row> DF1 = spark
.read().format("csv")
.option("header", "true")
.option("delimiter", "\t")
.load("C:/hive/Orders_[0-9]*.csv");
错误代码:
Error starting ApplicationContext. To display the auto-configuration report re-run your application with 'debug' enabled.

下面的代码在spring Boot 中工作良好,当路径与确切的文件名一起给出时。
Dataset<Row> DF1 = spark
.read().format("csv")
.option("header", "true")
.option("delimiter", "\t")
.load("C:/hive/Orders_000001.csv");
如何解决这个问题?

这里有一个可能的解决方案
1.自行下载Hadoop(如果来自Spark)
1.从https://github.com/cdarlint/winutils下载适用于Windows的匹配Hadoop版本文件
1.解压缩文件(例如C:\hadoop)。确保目录结构类似于此
C:\hadoop\bin\winutils.exe
1.将环境变量
HADOOP_HOME
设置为C:\hadoop
1.将Hadoop添加到Path env变量:
%HADOOP_HOME%\bin
1.将
hadoop.dll
复制到Windows\System32
(可能不需要)1.重启系统
System.setProperty ("hadoop.home.dir", "C:/hadoop/" );
System.load ("C:/hadoop/bin/hadoop.dll");
