Subject [jira] Updated: (PIG-6) Addition of Hbase Storage Option In Load/Store Statement
Date Fri, 05 Dec 2008 10:02:44 GMT

     [ https://issues.apache.org/jira/browse/PIG-6?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Samuel Guo updated PIG-6:
-------------------------

    Attachment: PIG-6.patch

Attach my patch. 

Now it implements the function of loading a table from hbase into pig to do data-processing.

Usage: 
> register ./hbase-0.18.1.jar
> raw = load 'tablename' using org.apache.pig.backend.hadoop.hbase.HBaseStorage('f1:c1
f2:c2 f3:c3') as (field1, field2, field3);

the parameter of  *HBaseStorage*  is a column list delimited by space.

Welcome comments on my patch. so I can know how to improve it.

:-)

> 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.
