Granting User Permissions for the Amazon EMR Environment
Granting User Permissions for the Amazon EMR Environment
After you install MDM Big Data Relationship Management in the Amazon EMR environment, you can use the default user name,
hadoop
, or other user names to access the MDM Big Data Relationship Management batch jobs.
If you use
hadoop
as the user name, you do not require any additional permissions to run the batch jobs. If you use other user names, ensure that you grant the write permission to the working directory in HDFS and the read permission to the input data in HDFS before you run the batch jobs.
