Re: Facing Issue while connecting with HDFS

[digvijayp]

Hi Bryan,

I am saying that in our HDFS cluster specific user have the
permission(superuser) to access it.So when ever we have to do any operation
on cluster we need to first login by our id and then superuser and then we
can access the cluster.
When I trying to connect to NIFI with HDFS cluster it is trying to login by
my id and then not with the superuser .Due to which I am getting the
authentication issue,so I need to provide superuser credential in the nifi
so that it will first login and then do connection.not sure where do I add
these detail in the nifi?

Thanks for support.

Hi Bryan,
So in edge node approach how data sent in site-to-site ?I mean to say is it
using any protocol to transfer it like FTP,SFTP.
As you are saying If both clusters can fully talk to each other than you
don't need this edge node approach, you could just have a NiFi instance, or
cluster, that pulls from one HDFS and pushes to the other.
so my query is we have to use FetchHDFS/getHDFS process which get data from
HDFS to local machine and putHDFS process which load data from local machine
to HDFS.I dont have yo use the local machin in between .So how can we manage
the transfer data without using local machine? Where can we do such
configuration in nifi? 

Thanks in advance.
