Summary: Capture output in JSON format
Key: OOZIE-3248
URL: https://issues.apache.org/jira/browse/OOZIE-3248
Project: Oozie
Issue Type: New Feature
Components: action
Affects Versions: 5.0.0
Reporter: Andras Piros
Today the user can specify to capture output of Oozie actions, and reuse that
in EL expressions in consecutive actions of the same workflow.
As per [*Oozie workflow functional
specification*|https://oozie.apache.org/docs/5.0.0/WorkflowFunctionalSpec.html]:

The capture-output element can be used to propagate values back into Oozie
context, which can then be accessed via EL-functions. This needs to be written
out as a java properties format file. The filename is obtained via a System
property specified by the constant {{oozie.action.output.properties}}.
{quote}
Let the output happen in following formats:
# first and foremost, {{java.util.Properties}} format
# if output is not parseable, fall back to JSON parsing
# if output is not parseable, throw an {{Exception}} like before
