-------------------------------------
Summary: Agent-side command-*.json files should optionally be
deleted when no longer needed by the command
Key: AMBARI-24228
URL: https://issues.apache.org/jira/browse/AMBARI-24228
Project: Ambari
Issue Type: Bug
Components: ambari-agent
Affects Versions: 2.1.0
Reporter: Robert Levas
Assignee: Robert Levas
Fix For: 2.7.0
Agent-side _command JSON_ files ({{command-*.json}}, {{status_command.json}})
should optionally be deleted when no longer needed by the command. One reason
for this is to reduce the risk of leaking sensitive data stored at plaintext in
the _command JSON_ files.
Currently the _command JSON_ files are stored on disk in
/var/lib/ambari-agent/data. These files may be cleared out over time, but
there is a need to have them removed as soon as they are no longer needed.
To do this, a retention policy may be defined so that the Ambari agent behaves
accordingly:
* {{keep}}
** No automatic removal is performed
** This is the default behavior
* {{remove}}
** The _command JSON_ file are remove as soon as the command completes
* {{remove_on_success}}
** The _command JSON_ files are remove as soon as the command *successfully*
completes
** The _command JSON_ files are not removed on failure conditions
