Hi, Samuel

    Thankx very much for your new patch.
    There are some problem when i used it as the following,

1. create table src(key int, value string);
ok
2. LOAD DATA LOCAL INPATH './examples/files/kv1.txt' OVERWRITE INTO TABLE src;
ok
3. CREATE TABLE hbase_table_1(key int, value string) 
ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.hbase.HBaseSerDe' 
WITH SERDEPROPERTIES ("hbase.columns.mapping" = "cf:string"
) STORED AS HBASETABLE;
ok
4.FROM src INSERT OVERWRITE TABLE hbase_table_1 SELECT *;
FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.ExecDriver

I found error in the m/r map process, just as the following,
