I need to apply patch to Release 0.19.1,
In order to deploy I need to compile again and create a new
Hadoop-*-core.jar
The development environment consists of Windows XP , Eclipse 3.4 (IBM RAD
7.5)
The target platform is AIX 5.3.
I have extracted the release from the SVN, and tried to exeucte the ANT
build (project -> Build project)
Problem encontered:
1. Failure to carry out target <compile-core-classes>, it seem that the
<jsp-compiler> macro fails to find org.apach.log4j.Category class.
Resolution: Since the release comes with log4j ver 1.2.15 which does
not include this class, I have commented out the <jsp-compiler> tasks,
this has allowed me to continue processing.
Help: How should I include the web class (war) into the newly
compiled jars ?
2. Failure to compile <compile-contrib> ->>> <eclipse-plugin> project,
fails.
Resolution: It seems that the build.xml under
src/contrib/eclipse-plugin direcotory uses property ${eclipse.home}
This property should refernce the plugin jars,
However, my platform places the plugin jars in a
different location !
I have carried out the following steps to make it
work:
- Under Windows->Preferences->Ant->Runtime in the Property tab, I have
added a new variable eclipse.homeplugins=<MY_PLUGIN_PATH>
- In src/contrib/build-contrib.xml I have added the following condition
<condition property="eclipse_plugin.home" value="${eclipse.homeplugins}"
else="${eclipse.home}">
<and>
<isset property="${eclipse.homeplugins}"/>
</and>
</condition>
-
In src/contrib/eclipse-plugin/build.xml I have changed the <path
id="eclipse-sdk-jars"> into the following:
<path id="eclipse-sdk-jars">
<!-- The following original is REMOVED, fileset
dir="${eclipse.home}/plugins/" -->
<fileset dir="${eclipse_plugin.home}/plugins/">
.....
</fileset>
</path>
Help: The build fails, after 100 of such erros (beside avoid compiling
this project)
