Subject [Hadoop Wiki] Update of "InvalidJiraIssues" by SteveLoughran
Date Thu, 24 Jan 2013 05:29:51 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "InvalidJiraIssues" page has been changed by SteveLoughran:

all about Invalid Hadoop JIRA issues

New page:
This page tries to explain why some issues on the Apache Hadoop JIRA categories get closed

The JIRA server at https://issues.apache.org/jira/ is used for two things

 1. discussing and co-ordinating feature development of Apache Hadoop. We welcome people who
want to get involved with this.
 1. reporting fixing bugs in the code

What it is not is ''a way of people reporting their "I couldn't get Hadoop to work" problems''.

Given that Hadoop is used on thousands of machines by companies like Yahoo!, Facebook and
eBay, we are reasonably confident that Hadoop works on:
 * well configured servers.
 * well configured networks.
 * well configured Hadoop installations.

If Hadoop does not work for you, then these are the likely problems -your problems related
to local configurations.

'''These are not bugs in Hadoop -so do not file bugs on JIRA about them'''

Bug reports of the form "I can't get Hadoop to work", are going to be closed as invalid, unless
there is clear evidence that the problem exists in an Apache release. 

Which raises another issue. JIRAs cannot be filed against distributions of Hadoop that aren't
bundling the Apache releases of Hadoop artifacts. We can't, because we don't all track what
those changes are. 

 * [[http://wiki.apache.org/hadoop/Distributions%20and%20Commercial%20Support|Vendors of Hadoop-derived
products]] provide their own mailing lists and forums. Please try there.
 * The [[http://hadoop.apache.org/general_lists.html#User|hadoop-user]] mailing list is the
place at Apache where discussions on installation and configuration problems should take pace.
Not JIRA, not hadoop-general. Not the -dev lists. Asking the developers for help on configuring
your system is like emailing the linux-kernel mailing list for help getting /etc/fstab right.
 * There are a number of quality [[Books|Books on Hadoop]]. These are worthwhile investment.
 * The source is all there [[http://svn.apache.org/viewvc/hadoop/common/trunk/|for you to

This may seem unfair for the developers not to care about your "critical" issue and close
it as invalid, despite the fact they are clearly the experts in Hadoop internals. However
they -we- are busy trying to build the future of Hadoop, ''the operating system for data''.
Most of the people working on this are being paid to do so, either from companies whose business
is built around selling supported Hadoop-based products, or from people who use in production
internally. None of these people have the time to help you -because if they did help everyone
with a problem, they'd never get anything done.

Those developers who are working full time for downstream redistributors of Hadoop works are
being paid through support revenue -and their companies have support teams who will help -as
can others on the [[http://wiki.apache.org/hadoop/Distributions%20and%20Commercial%20Support|Distributions
and Commercial Support]] page. Those developer using Hadoop on internal projects probably
get to field lots of internal support calls -which keeps them busy enough.

That's why your JIRA issue was closed. It's not that the developers don't care that you can't
get Hadoop to work -it's that they aren't the right people to ask.
