Subject [jira] [Commented] (CRUNCH-4) Create profiles for Crunch builds based on Hadoop 1.0 and Hadoop 2.0
Date Thu, 09 Aug 2012 22:47:19 GMT

    [ https://issues.apache.org/jira/browse/CRUNCH-4?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13432265#comment-13432265

Josh Wills commented on CRUNCH-4:
---------------------------------

So I downloaded the 0.94.1 HBase release and verified that Crunch patches tests with it--
*IF* you download the HBase source files and compile it yourself using:

mvn clean install -Dhadoop.profile=2.0 -DskipTests

and then run crunch as:

mvn clean verify -Dcrunch.platform=2

The default maven jars go against the 1.0.x version of Hadoop and will fail if you run them
with Hadoop 2.0.0-alpha. I'm not sure of the best way to message that to people short of putting
a note on the website, at least until the HBase guys release a maven version that is compiled
against 2.0.0-alpha. In any case, I'd like to integrate Rahul's changes so that we can commit
this, break the HBase stuff into its own subcomponent, finish CRUNCH-16, and release.

> We need to create two Maven build profiles for Crunch, one that depends on Hadoop 1.0
(probably 1.0.3 for Hadoop and 0.90.5 for HBase) and Hadoop 2.0 (2.0.0-alpha for Hadoop and
a stable 0.92.x for HBase.)
