val destinationPath = "file:\\E:\\newcode\\MyFirstProject\\data\\stockresult.txt" ;
FileSystem fs = FileSystem.get(URI.create(path),conf);
writer = new BufferedWriter(new OutputStreamWriter(fs.create(new Path(path))));
if(null!=writer){
    logger.info("[HdfsOperate]>> initialize writer succeed!");
}

出现了下面的错误：

Exception in thread “main” java.lang.IllegalArgumentException: Illegal character in opaque part at index 5: file:\E:\newcode\MyFirstProject\data\stockresult.txt
at java.net.URI.create(URI.java:852)

问题是Uri格式没写对，写成下面这样就对了

val destinationPath = "file:/E:/newcode/MyFirstProject/data/stockresult.txt" ;
