Thanks all...
btw, s3n load works without any issues with spark-1.3.1-bulit-for-hadoop
2.4
I tried this on 1.3.1-hadoop26
> sc.hadoopConfiguration.set("fs.s3n.impl",
"org.apache.hadoop.fs.s3native.NativeS3FileSystem")
> val f = sc.textFile("s3n://bucket/file")
> f.count
No it can't find the implementation path. Looks like some jar is missing ?
java.lang.RuntimeException: java.lang.ClassNotFoundException: Class
