> The HiveQL way of creating a HBase table looks something like 
> REATE TABLE bla(id_1 type_1, id_2 type_2..., id_n type_n)
> STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
> WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf:id_2, cf:id_3") TBLPROPERTIES
("hbase.table.name" = "blah");
> But in most cases huge amounts of this can be assumed from the original table description.
In fact in most cases, especially ones when that data was imported from MySQL it is trivial
to generate at least one HBase backing for that data. I currently wrote a python script which
our users can use to make things simpler. Would anyone be interested in that script? Would
it make sense to make it easy from Hive? I hate to add reserved words so any suggestions are
welcome.
