Subject Error : - No filesystem for scheme: spark
Date Mon, 02 Nov 2015 06:48:22 GMT
Can someone tell me at what point this error could come?

In one of my use cases, I am trying to use hadoop custom input format. Here
is my code.

val hConf: Configuration = sc.hadoopConfiguration
hConf.set("fs.hdfs.impl",
classOf[org.apache.hadoop.hdfs.DistributedFileSystem].getName)
hConf.set("fs.file.impl",
classOf[org.apache.hadoop.fs.LocalFileSystem].getName)var job = new
Job(hConf)
    FileInputFormat.setInputPaths(job,new
Path("hdfs:///user/bala/MyBinaryFile"));


    var hRDD = new NewHadoopRDD(sc, classOf[RandomAccessInputFormat],
        classOf[IntWritable],
        classOf[BytesWritable],
        job.getConfiguration()
        )

    val count = hRDD.mapPartitionsWithInputSplit{ (split, iter) =>
myfuncPart(split, iter)}

The moment I invoke mapPartitionsWithInputSplit() method, I get the
below error in my spark-submit launch


15/10/30 11:11:39 WARN scheduler.TaskSetManager: Lost task 0.0 in
stage 0.0 (TID 0, 40.221.94.235): java.io.IOException: No FileSystem

at org.apache.hadoop.fs.FileSystem.getFileSystemClass(FileSystem.java:2584)
at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2591)
at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:91)

Any help here to move towards fixing this will be of great help



Thanks
