無法找到將文件從HDFS附加到電子郵件MimeBodyPart的方式。 這是我迄今的嘗試。我試圖使用FileDataSource和URLDataSource,但沒有運氣。將文件從HDFS附加到javax.mail電子郵件

val attachmentPart = new MimeBodyPart() 
val filePath = "FILE_PATH" 
val fileName = s"FILE_NAME_${date}.html" 

val fs = FileSystem.get(sctx.hadoopConfiguration) 
val fullURL = fs.getFileStatus(new Path(filePath+fileName)).getPath.toUri.toURL 
//val fullFilePath = fs.getFileStatus(new Path(filePath+fileName)).getPath.toString 

val source = new URLDataSource(fullURL) 
//val source = new FileDataSource(fullFilePath) 
attachmentPart.setDataHandler(new DataHandler(source)) 
attachmentPart.setFileName("file name") 

我得到的一個URLDataSource的情況下,出現以下錯誤:

Exception in thread "main" java.net.MalformedURLException: unknown protocol: hdfs 
+0

嘗試註冊Hadoop的FsUrlStreamHandlerFactory處理 '進口org.apache.hadoop.fs.FsUrlStreamHandlerFactory URL.setURLStreamHandlerFactory(新FsUrlStreamHandlerFactory())' –

嘗試註冊了Hadoop的FsUrlStreamHandlerFactory處理與架構HDFS的URL。

import org.apache.hadoop.fs.FsUrlStreamHandlerFactory 
import java.net.URL 
URL.setURLStreamHandlerFactory(new FsUrlStreamHandlerFactory())

感謝@胭脂一個它的工作。 –
