Hi Sugato,
Do you want to read the data from hdfs? From the log it seems like
you're reading data from a "RawLocalFileSystem". Maybe you need to check if
you have set your default file system in the configuration correctly (
fs.default.name or fs.defaultFS, depending on your hadoop version)?
Thanks,
-Jing
