[jira] [Created] (BIGTOP-678) make hive TestJdbcDriver more robust
Wing Yew Poon created BIGTOP-678:
------------------------------------
Summary: make hive TestJdbcDriver more robust
Key: BIGTOP-678
URL: https://issues.apache.org/jira/browse/BIGTOP-678
Project: Bigtop
Issue Type: Improvement
Components: Tests
Affects Versions: 0.3.0, 0.4.0
Reporter: Wing Yew Poon
Assignee: Wing Yew Poon
Fix For: 0.5.0
I plan to attach a patch to make TestJdbcDriver more robust, by parameterizing the wait time for the hive server to be up (it is currently hardcoded to 1 second, which may not be long enough) and by introducing a timeout to the test method (in my experience, if for some reason hive is not up or otherwise able to respond successfully, the test hangs).

Wing Yew Poon commented on BIGTOP-678:
--------------------------------------
Bruno, on second thoughts, I think I'd leave it the way it is for now. Using Integer.getInteger(String, int) would indeed be easier. However, using System.getProperty(String) makes it easier later to find all the properties used by the tests. Right now, we don't have a way in the tests to specify a contract, in particular, what are the inputs (possibly optional) to a test, which typically is done by setting system properties. Until we have some kind of annotation or other way (even just a convention) for specifying such a contract, I'd leave the property in a System.getProperty(String) call.

What about wrapping it in a util function or something similar? If we get this sort of code all over the place, it is not going to be very easy to follow.

Wing Yew Poon commented on BIGTOP-678:
--------------------------------------
What I meant was that, afaik, tests that use or depend on system properties or environment variables to parameterize behavior contain System.getProperty() or System.getenv() calls, so we can currently determine what the set of properties and variables are by grepping for System.getProperty and System.getenv in the test code. If instead, I start using Integer.getInteger(), then that would be one more (less obvious) thing to keep track of to grep for. You can imagine at least writing a tool (script) to come up with the "contract" (set of properties and variables) even in the current imperfect state of things. Changing the code to use Integer.getInteger() makes writing this tool a little more complex.

Bruno Mahé commented on BIGTOP-678:
-----------------------------------
What I meant was that, being able to grep on the properties being used is fair.
But if the cost of it is to have such template copy/pasted in such form all over the place, I am not sure I will go along. It's fine for a one time patch, but wouldn't work if applied to the whole code base.
Hence my suggestion to refactor it or to wrap it up in a util function you could grep on as well.
