Subject [jira] Updated: (HADOOP-6248) Circus: Proposal and Preliminary Code for a Hadoop System Testing Framework
Date Thu, 10 Sep 2009 18:06:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6248?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Alex Loddengaard updated HADOOP-6248:

    Attachment: HADOOP-6248_v2.diff

Attaching a new patch with a few modifications:
# Changed the canned distribution, which was previously Cloudera's distribution, and is now
vanilla Hadoop.
# Changed hdfs-basic tests to not use /etc/passwd and instead create a temporary file
# bin/circus will now exit with the appropriate exit status when tests pass or fail

I should also say a little about my intentions of this patch, and Circus in general.  I claim
that the code I've attached is preliminary, and my proposal has lots of open questions.  I'm
confident that Circus, as it exists right now, is already useful for Hadoop users and QA engineers.
 My posed questions are intended to gather useful feedback to improve Circus even more.  I'd
be completely happy if the preliminary code made it into trunk, with the expectation that
I will continue to submit further patches to improve Circus.

> This issue contains a proposal and preliminary source code for Circus, a Hadoop system
testing framework.  At a high level, Circus will help Hadoop users and QA engineers to run
system tests on a configurable Hadoop cluster, or distribution of Hadoop.  See the comment
below for the proposal itself.
