The following page has been changed by DougCutting: http://wiki.apache.org/hadoop/HowToRelease The comment on the change is: updated for addition of jdiff ------------------------------------------------------------------------------ svn commit -m "Merge -r R1:R2 from trunk to X.Y branch. Fixes: HADOOP-A, HADOOP-B." }}} + = Build Requirements = + + To build an official release, you must: + + 1. Use a 64-bit Linux system, so that we can build both 32- and 64-bit native code. + + 1. Have a recent version of Eclipse installed, so that the eclipse plugin will build. + + 1. Have Owen's patched version of JDiff installed, attached to [https://issues.apache.org/jira/browse/HADOOP-3532 HADOOP-3532]. + = Building = - 1. Build the release & run unit tests. Note that releases are normally built on 64-bit Linux, so that they include the native code for that platform. Also, folks who build releases should install eclipse, so that the eclipse plugin can be included in releases, pre-compiled. {{{ + 1.

Send announcements to the user and developer lists once the site changes are visible. 1. In Jira, ensure that only issues in the "Fixed" state have a "Fix Version" set to release X.Y.Z. 1. In Jira, "release" the version. Visit the "Administer Project" page, then the "Manage versions" page. You need to have the "Admin" role in Hadoop Core's Jira for this step and the next.
