-----------------------------------------
Summary: Update sbin/start-* and sbin/stop-* to be smarter
Key: HADOOP-13673
URL: https://issues.apache.org/jira/browse/HADOOP-13673
Project: Hadoop Common
Issue Type: Bug
Components: scripts
Affects Versions: 3.0.0-alpha1, 3.0.0-alpha2
Reporter: Allen Wittenauer
Assignee: Allen Wittenauer
As work continues on HADOOP-13397, it's become evident that we need better
hooks to start daemons as specifically configured users. Via the
(command)_(subcommand)_USER environment variables in 3.x, we actually have a
standardized way to do that. This in turn means we can make the sbin scripts
super functional with a bit of updating:
* Consolidate start-dfs.sh and start-secure-dns.sh into one script
* Make start-*.sh and stop-*.sh know how to switch users when run as root
* Undeprecate start/stop-all.sh so that it could be used as root for production
purposes and as a single user for non-production users
