Subject [jira] Commented: (HADOOP-6295) Build process from tarball is flawed
Date Mon, 05 Oct 2009 10:04:31 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6295?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12762133#action_12762133
] 

Steve Loughran commented on HADOOP-6295:
----------------------------------------

I'm not going offer any of my limited time to help with this, but I will note that I've worked
on build files in the past that <exec> a native tar -xf and then run the build file
in the expanded directory just to check that the redistributable works. That is, it's possible
to automated the test that your redistributables build.

That said, I'm normally reluctant to provide redists that compile, as encouraging people to
check out from SVN actually put them half-way to doing a real fix to correct a problem -lets
you answer the "does the problem go away in SVN_HEAD" question, and if the answer is no, puts
them in a place to do the patch. Perhaps native code is special in that you do need to rebuild
it for different target platforms. In which case, perhaps someone needs to be thinking of
source RPM/deb packages.

> Currently, the natively compiled components have a requirement of building from within
ant.  To make matters worse, after talking this over with Lee, it appears that the ant build
assumes to be executed from a svn-checkout and not from the tarballs that are generated. 
We need to
> a) start packaging up the svn repo trees as src tarballs
> b) separate out the compiled bits out from underneath ant completely
> c) be able to create real builds from the tarball
> As an admin, I shouldn't have to reach for svn to make Hadoop work optimally on non-Linux.
