Error running "hdfs.put()" in RHadoop

Question

I am using RHadoop for my project on sentiment analysis. When I try to run hdfs.put() I am recieving the following error:

Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl,  :

Can anyone help me with this?

Answer 1

Its a permission denied error. You are running the command as user. Just run su hduser before your command (the error states that hduser has the required permissions). Or grant user the required permissions with chmod.

Answer 2

user don't have permission to access the /. Try by changing the path to user home
