reading files on HDFS /s3 in sparkR -failing

[roni]

I am trying this -

 ddf <- parquetFile(sqlContext,  "hdfs://
ec2-52-26-180-130.us-west-2.compute.amazonaws.com:9000/IPF_14_1.parquet")

and I get path[1]="hdfs://
ec2-52-26-180-130.us-west-2.compute.amazonaws.com:9000/IPF_14_1.parquet":
No such file or directory


when I read file on s3 , I get -  java.io.IOException: No FileSystem for
scheme: s3


Thanks in advance.
