This is likely a result of how things are now being built post project-split, but previously, for the hadoop-0.20.x releases there was a top level build.xml file which would orchestrate building the sub-projects which were split underneath the src directory, resulting in a final hadoop-20.x-core.jar. I see now each sub-project (common, hdfs and mapred) has its own subdirectory off of the root, as opposed to forking under the src/ directory and in turn their own sub-project jar files and there is now no aggregated hadoop-x-core.jar file.
I also saw Tom's JIRA with the 0.21 build scripts. My questions are: 1) Is this the way we're going to be building going forward for the foreseeable future? 2) Could we consider still keeping a top level build file (i.e committing a variant of tom's scripts) that orchestrates the building of all the sub-projects? Kind regards Steve Watt
