Subject Re: about using HBase?
Date Thu, 17 Jan 2008 08:50:29 GMT
Thank you for your help!

You metioned hadoop-0.16.* , but I still use hadoop-0.15 ,I can't see
hadoop-0.16.* in the http://lucene.apache.org/hadoop/releases.html,
and I haven't found the org.apache.hadoop.hbase.hql . .So I'm not sure
I use the correct edition.
