> The property name for Hbase table mapping is changed from hbase.table.name to hbase.mapreduce.hfileoutputformat.table.name
in HBase 2.
> We can include such upgrade for existing hbase-based tables in DB upgrade script to automatically
change such values.
> For the new tables, the query will be like:
> create table hbase_table(key int, val string) stored by 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
with serdeproperties ('hbase.columns.mapping' = ':key,cf:val') tblproperties ('hbase.mapreduce.hfileoutputformat.table.name'
= 'positive_hbase_handler_bulk')
