Does the "package" command star= t another YARN cluster?


On "http://giraph.apache.org/p= agerank.html",
(1) The last step, "Building and compiling page rank", is mi= ssing.
(2) I successfully compiled the giraph-examples and have a= working Hadoop YARN, how do I run the Page Rank program?

Many thanks,

= I posted the most recent "correct" way to build pure-YARN Giraph = against any hadoop version on GIRAPH-688 here:



mvn -Dhadoop.version=3D2.0.3-alpha -Phadoop_yarn clean = install

if you want to just compile and not create= our build products as in your example, replace "clean install" w= ith "compile". -P profile should be "hadoop_yarn" for p= ure YARN builds, and "hadoop.version" appears as the part of the = hadoop version you see on the Apache Hadoop download site, -after- the &quo= t;hadoop-" part. So "hadoop-2.0.3-alpha" becomes for us &quo= t;-Dhadoop.version=3D2.0.3-alpha"

To build Giraph so that it can run on a YARN-enabled Ha= doop cluster that -also- uses MapReduce v2 as the interface to the cluster = (Giraph will still think its running on MapReduce, not YARN) you might do t= his:

mvn -Phadoop_2.0.3 clean install

If you want to see how we label build profiles vs. "hadoop.version&= quot; in Giraph builds, check our POM.xml files

Thanks! Sorry for the confusion, this is a confusing th= ing since there are 2 ways to "run Giraph on YARN" as detailed ab= ove.
