Hi, Could you just trying one thing. Make a directory any where out side cloudera and than try the same write.
Suppose the directory made is testWrite. do r.saveAsTextFile("/home/testWrite/") I think cloudera/tmp folder do not have a write permission for users hosted other than the cloudera manager itself. Thanks.
