Hive-Hbase integration require Hbase in Pseudo distributed??
Alok Kumar 2011-12-02, 08:30
Hi,

Does Hive-Hbase integration require Hbase running in pseudo-distributed
mode?

I've build my Hadoop following this article
http://www.michael-noll.com/blog/2011/04/14/building-an-hadoop-0-20-x-version-for-hbase-0-90-2/
and  have already replaced Hbase jar files accordingly..

I'm getting this error..

hive> !jps;
5469 Jps
4128 JobTracker
3371 Main
4346 TaskTracker
5330 RunJar
4059 SecondaryNameNode

'org.apache.hadoop.hive.hbase.HBaseStorageHandler' with
serdeproperties("hbase.columns.mapping" = ":key,cf1:val") tblproperties ("
hbase.table.name" = "xyz");
