------------------------------
Summary: Add command-line driven provenance tools
Key: NIFI-635
URL: https://issues.apache.org/jira/browse/NIFI-635
Project: Apache NiFi
Issue Type: Improvement
Components: Tools and Build
Reporter: Adam Taft
Priority: Minor
Create a suite of command line driven tools suitable to perform dataflow
queries against the provenance reporting engine.
Rationale: dataflow managers are routinely tasked to find and isolate the
lifecycle endpoints of a flowfile instance within a given flow. Often the
history of a single flowfile can be followed using the provenance user
interface. However, the operator is limited only to the user interface, which
prevents him/her from composing and chaining unix-style commands, such as grep,
sed, cut, etc.
Recommendation: extract the query side of the provenance reporting engine into
a separate library; create a CLI package to execute a set of common or advanced
queries against the provenance backend; emit results using a text based output
in order pipe to other unix style tools.
