All right, I remove cloudera totally and install spark manually on bare Linux system and now r.saveAsTextFile(…) works.
Thanks.

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.

For instance in your case just do r.saveAsTextFile("home/cloudera/tmp/out1") Dont use file This will create a folder with name out1. saveAsTextFile always write by making a directory, it does not write data into a single file. Incase you need a single file you can use copyMerge API in FileUtils. FileUtil.copyMerge(fs, home/cloudera/tmp/out1, fs,home/cloudera/tmp/out2 , true, conf,null); Now out2 will be a single file containing your data. fs is the configuration of you local file system.
