Encrypting Communication with the HDFS Cluster
For the clients authenticated to access the HDFS cluster using Kerberos, you can encrypt their communication with the HDFS cluster by setting values of certain parameters in the core-site.xml and hdfs-site.xml files.
Important:
Software AG recommends that you maintain identical versions of both core-site.xml and hdfs-site.xml on the HDFS cluster and the computer on which webMethods Adapter for HDFS is running.
1. In core-site.xml, set the value of the hadoop.rpc.protection property to privacy.
2. In hdfs-site.xml, set the value of the dfs.encrypt.data.transfer property to true.
