-----------------------------------
Summary: Better logging for SshActionExecutor and extended HA
capability when calling to remote host
Key: OOZIE-3183
URL: https://issues.apache.org/jira/browse/OOZIE-3183
Project: Oozie
Issue Type: Improvement
Components: action
Affects Versions: 5.0.0b1
Reporter: Andras Piros
Assignee: Andras Piros
Fix For: 5.0.0
In some High Availability environments, when an SSH action's
{{SshActionExecutor#start()}} runs on another node than
{{SshActionExecutor#check()}}, it can happen that due to network bandwidth
reasons calling {{Process#exitValue()}} is not enough - but calling
{{Process#waitFor()}} is better.
Also, for better error root cause analysis, enhance logging along
{{SshActionExecutor}} for the critical parts.
