Subject Re: integrate hbase over hadoop in eclipse IDE
Date Mon, 12 Sep 2011 16:55:26 GMT
(answering on this thread with plain reply on dev@, although other 
thread opened on user@ with answers from JD).

Hi Vamshi,

Before running HBase withing eclipse, did you successfully run it from a 
distribution?

To achieve this, you can download the dist, or if you like, run 'mvn 
package' on a fresh svn checkout (tar.gz will be in target folder).

Btw, it is not recommended to run hbase on hadoop-0.20.203 (you can 
loose data):
- http://hbase.apache.org/book/hadoop.html
- http://markmail.org/message/yro25zqfjqvajeby
- http://markmail.org/message/jfub7b4noqf32j2i

If you really want to test/hack agains 0.20.203, you can build hbase 
with 'mvn package -Dhadoop.profile=23'

The logic for 0.20.203 and 0.20 should be the same: replace the hadoop 
jar with the one shipped by hbase.

So better to try first with a dist (downloaded or packaged), and then 
from eclipse. Could be easier as it will serialize/split the problems.

Thx.
