Hi ! I wanted to build and run the hadoop code itself from eclipse . I followed the instructions in http://wiki.apache.org/hadoop/EclipseEnvironment as : 1) I have checked out the hadoop release from http://svn.apache.org/repos/asf/hadoop/common/tags/release-0.21.0/ from eclipse europa. 2) I have got common, hdfs and mapreduce folders under the project main directory. 3) Since i am behind a proxy i added proxy stuff to build.xml files in these 3 folders and did ant builds in eclipse which were successful. 4) Some additional things were mentioned to run tests in eclipse: selecting build dir(i have selected $Workspace/$project/build dir) and added tools.jar.
When i try to run as Java Application i get error: Illegal option: a Usage: jar {ctxui}[vfm0Me] [jar-file] [manifest-file] [entry-point] [-C dir] files ... I don't know how to go about further ? Any help ? Thanks, Arun
