Tom White commented on HADOOP-5107:
-----------------------------------
A few comments after playing with this:
* With these changes we should be able to use Ivy's support of transitive
dependencies, so (amongst other things) we could remove the jets3t dependency
from HDFS. Cleaning up the direct dependencies probably belongs in a follow up
issue.
* I was having problems getting the build the use the version of Ivy it
downloads. This was due to an older version in ~/.ant which was being picked
up. It worked after I deleted it. (I just mention this in case others have this
problem - no changes are required to the patches.)
* I had to make a few changes to ivysettings.xml:
** Define a maven2.pattern (it was having problems retrieving the RAT jar
without it):
{code}
<property name="maven2.pattern"
value="[organisation]/[module]/[revision]/[module]-[revision]"/>
{code}
** Define a default username (empty), since without it you get the error "The
uri is in the wrong format" (for e.g.
/home/${username}/ivyrepo/commons-cli/commons-cli/1.1/ivys/ivy.xml):
{code}
<property name="username" value=""/>
{code}
> split the core, hdfs, and mapred jars from each other and publish them
> independently to the Maven repository
