Begin by creating a user account for the job execution user.
The user account must be created for all nodes comprising the DFS. The user name and the user ID must, therefore, be the same on all nodes. This is to achieve consistency at all nodes, because the DFS uses user IDs for control and Hadoop operates on the basis of user names.
Specify the group entered in the BDPP_HADOOP_DEFAULT_GROUP parameter of bdpp.conf as the group to which the newly created user account belongs.
Example
Create a user account for a user named bdppuser1.
The following conditions apply:
User name: bdppuser1
User ID: 1500
Group name: bdppgroup (the group specified in the BDPP_HADOOP_DEFAULT_GROUP parameter)
# useradd -u 1500 -g bdppgroup bdppuser1 <Enter>
