Subject Error while integrating Hive and Hbase
Date Wed, 21 Dec 2011 18:51:57 GMT
Hello all,

    I am trying to use Hbase and Hive together but facing some
problem..Whenever I am trying to create a table in Hbase through Hive
I am getting the following error -

hive> CREATE TABLE hbase_table_1(key int, value string)
    > STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf1:val")
    > TBLPROPERTIES ("hbase.table.name" = "xyz");
FAILED: Error in metadata:

I am using Hive-0.7.1 and the version of Hbase provided by Whirr is
0.89/20100924.
