Subject [jira] [Created] (HELIX-565) Quick Start Instruction Improvement
Date Wed, 04 Feb 2015 06:57:35 GMT
David Lloyd created HELIX-565:
---------------------------------

             Summary: Quick Start Instruction Improvement
                 Key: HELIX-565
                 URL: https://issues.apache.org/jira/browse/HELIX-565
             Project: Apache Helix
          Issue Type: Improvement
            Reporter: David Lloyd
            Priority: Minor



ISSUE:

Enhancement to instructions.

WEB-PAGE FOR INSTRUCTIONS:

http://helix.apache.org/0.7.0-incubating-docs/Quickstart.html

(but the 0.6.x instructions display the same issue).

TL;DR

The cluster is left running in a healthy state after the third node is killed. This is the
expected behaviour *however* I did not expect this and thought the test would end and return
to command line.

Instructions could be enhanced by noting "The cluster will continue to run until you stop
it with ^C or the machine you are running the quick start on is turned off."

DESCRIPTION

The quick start works very well for me and there is nothing *wrong* with the instructions
as such.

However, I did not understand the the quickstart test simply leaves the Helix managed clusters
going and does not return; I thought that was actually an error until I had a light bulb moment
about what was happening.

Perhaps add a comment at the end where the output is shown after the third node is killed
like: "The cluster will continue to run until you press ^C or the machine is turned off."
