How to acess to HDFS via R?

QUESTION

How to acess to HDFS via R?

Asked 2018-Dec-11 at 10:14

So, I am trying to connect to a HDFS server via R remotely on a Windows machine.

I use RStudio with the "rhdfs" package, however, and since I had to create the HADOOP_CMD environment variable, I downloaded the Hadoop to my machine in order to give the environment variables, and change the core-site.xml.

Previously I tried, sucessfully a connection the Kerberized Hive server with a Keytab.

Here is my code:

i figured out a solution to this.

If the server has the Kerberos authentication method, a keytab authentication can be useful to access the server. See How to connect with HIVE via R with Kerberos keytab?.

After that, it is need to Download to your machine, in this case, a Windows machine, the same version of Hadoop present in the cluster and place the Hadoop a Windows directory.

Then, to configure the Hadoop you need to follow these steps until the point "Hadoop Configuration". Step by step Hadoop 2.8.0 installation on Window 10

The Hadoop in the cluster contain some configuration files that will be used in your local machine. The files are the core-site.xml, yarn-site.xml, hdfs-site.xml. They contain the information about the cluster, such as the default FS, what type of credentials used in the Cluster, the Hostname and the Port used.

Additional: To use the Hostnames when connecting to Datanodes, you need to add these lines in the hdfs-site.xml file.
