Hi Pawan, ant -p (not for 0.23+) will tell you the available build targets.
Use mvn (maven) for 0.23 or newer -----Original Message----- From: Matt Foley [mailto:mfo...@hortonworks.com] Sent: Thursday, March 08, 2012 3:52 PM To: common-user@hadoop.apache.org Subject: Re: Why is hadoop build I generated from a release branch different from release build? Hi Pawan, The complete way releases are built (for v0.20/v1.0) is documented at http://wiki.apache.org/hadoop/HowToRelease#Building However, that does a bunch of stuff you don't need, like generate the documentation and do a ton of cross-checks. The full set of ant build targets are defined in build.xml in the top level of the source code tree. "binary" may be the target you want. --Matt On Thu, Mar 8, 2012 at 3:35 PM, Pawan Agarwal <pawan.agar...@gmail.com>wrote: > Hi, > > I am trying to generate hadoop binaries from source and execute hadoop > from the build I generate.
