      The secure user variables have been changed to be consistent with the rest of the environment variable changes:

      |:---- |:---- |
      | HADOOP\_SECURE\_DN\_USER | HDFS\_DATANODE\_SECURE\_USER |
      | HADOO\P_PRIVILEGED\_NFS\_USER | HDFS\_NFS3\_SECURE\_USER |

    Description

      Post-HADOOP-13341 and (more importantly) HADOOP-13673, there has been a major effort on making the configuration environment variables consistent among all the projects. The vast majority of vars now look like (command)(subcommand)(etc). Two hold outs are HADOOP_SECURE_DN_USER and HADOOP_PRIVILEGED_NFS_USER.

      Additionally, there is

      • no generic handling
      • no documentation for anyone
      • no safety checks to make sure things are defined

      In order to fix all of this, we should:

      • deprecate the previous vars using the deprecation function, updating the HDFS documentation that references them
      • add generic (command)_(subcommand)_SECURE_USER support
      • add some verification for the previously mentioned var
      • add some docs to UnixShellGuide.md
