We have created a process to integrate with HDFS, and are trying to push a file to the HDFS Directory. In the HDFS connector, we only have the option of Username, and no password. We were going through the forum, and we found a statement which says "The user's identity is picked up from the caller process user identity.". Now is this the user that we use to login to the Boomi Platform that we need to provide in the connector? Or, should it be the user created in Hadoop? Does the user require any specific authorization to write the file to HDFS?
