The following page has been changed by MarkButler: http://wiki.apache.org/lucene-hadoop/EclipseEnvironment ------------------------------------------------------------------------------ === Configuring Eclipse to build Hadoop === - Building all of Hadoop in Eclipse is a little complicated because there are some DDL files used by the tests that need to compiled first. Therefore it is necessary to configure Eclipse to call part of the Ant script to build these, and have two build directories, one for the Ant script, the other for Eclipse, as you need to include the classes built by Ant on the library path and Eclipse forbids circular references. + If you want to build all of Hadoop in Eclipse, including contributions, then there are some [http://lucene.apache.org/hadoop/api/org/apache/hadoop/record/package-summary.html#skip-navbar_top DDL] files used by the tests that need to compiled first. One strategy is to configure Eclipse to call part of the Ant script to build these, and have two build directories, one for the Ant script, the other for Eclipse, as you need to include the classes built by Ant on the Eclipse library path and circular references are forbidden.
