hi Rajesh,

The rw-rw-r are the read-write permissions . I'd recommend this link to further understand the linux permissions and how they can be set http://www.linux.com/learn/tutorials/309527-understanding-linux-file-permissions

The commands for putting and getting files into hdfs are provided in this below link on Dezyre "Assignment 2 - Practice HDFS Commands "
