Subject Re: 'hbase.client.scanner.caching' default value for HBase 0.90.6?
Date Mon, 28 Oct 2013 13:04:43 GMT
Hi Ted -

You should benefit from using this link [0] to follow Nutch and HBase
integration. Link [1] would be the one you can download a production
release version of Nutch 2.2.1 that has HBase dependency.

Link [0]  http://wiki.apache.org/nutch/Nutch2Tutorial
Link [1]  http://www.eng.lsu.edu/mirrors/apache/nutch/2.2.1/

All the best!
