Subject [jira] Commented: (PIG-6) Addition of Hbase Storage Option In Load/Store Statement
Date Fri, 12 Dec 2008 01:42:44 GMT

Samuel Guo commented on PIG-6:
------------------------------

@Ben

> 1) you don't fill in the schema. hbase has schema right? it would be nice to fill it
in. 

All the values in hbase are interpreted as bytes array. I am not very sure about how to fill
the schema. I will check the code again.

> 2) i don't think you need to implement LoadFunc if you implement Slicer. 

hmm, I will remove the LoadFunc's null implementations.


Thanks, Ben :-)

> It needs to be able to load full table in hbase.  (maybe ... difficult? i'm not sure
yet.)
> Also, as described below, 
> It needs to compose an abstract 2d-table only with certain data filtered from hbase array
structure using arbitrary query-delimited. 
> {code}
> A = LOAD table('hbase_table');
> or
> B = LOAD table('hbase_table') Using HbaseQuery('Query-delimited by attributes & timestamp')
as (f1, f2[, f3]);
> {code}
> Once test is done on my local machines, 
> I will clarify the grammars and give you more examples to help you explain more storage
options. 
> Any advice welcome.
