-----------------------------------------
Summary: fix jsvc/secure user inconsistencies
Key: HADOOP-14202
URL: https://issues.apache.org/jira/browse/HADOOP-14202
Project: Hadoop Common
Issue Type: Improvement
Components: scripts
Affects Versions: 3.0.0-alpha2
Reporter: Allen Wittenauer
Assignee: Allen Wittenauer
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
