Subject [jira] [Commented] (HADOOP-6484) OSGI headers in jar manifest
Date Wed, 08 Feb 2012 14:41:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13203644#comment-13203644

Steve Loughran commented on HADOOP-6484:
----------------------------------------

# The patch sounds good; Karaf + Hadoop good too. 
# What is the test plan? I could imagine an existing in-junit test that looks for the manifest
entries, while presumably there is some karaf+hadoop thing too.
# Be aware that -from my own experience- what Hadoop does with security is strongly incompatible
with other java container security, which could cause problems, but you will need a security
manager to catch System.exit() calls.
# Regarding the JIRA assignment, I tried by giving you developer rights on the project, and,
when that didn't seem to do anything, put you in the all-developers group. I still can't seem
to assign it to you -perhaps you could log out, log in and try to assign it to yourself. Otherwise,
well, you are JIRA administrator so may stand a better chance of fixing this than I can.

> When using hadoop inside an OSGI environment one needs to change the META-INF/MANIFEST.MF
file to include OSGI headers (version and symbolic name). It would be convenient to do this
in the default build.xml. 
> There are no runtime dependencies.
> An easy way of doing this is to use the bnd ant task: http://www.aqute.biz/Code/Bnd
> <target name="build"> 
>    <taskdef resource="aQute/bnd/ant/taskdef.properties"
>       classpath="bnd.jar"/> 
>    <bnd 
>       classpath="src" 
>       eclipse="true" 
>       failok="false" 
>       exceptions="true" 
>       files="test.bnd"/> 
>  </target>
