Subject: No FileSystem for scheme: hdfs
To: cdh-user@cloudera.org


Hi All,

I am trying to invoke hadoop FileUtil.copyMerge from a piece of java code
but its comes up with error saying

java.io.IOException: No FileSystem for scheme: hdfs

I am stuck at this weird issue, Stack trace mentioned below, Hadoop 2.0 cdh
4.7 10 node cluster.

Looking out for the quickest response.
