Subject [jira] Commented: (PIG-1782) Add ability to load data by column family in HBaseStorage
Date Fri, 28 Jan 2011 17:36:44 GMT

    [ https://issues.apache.org/jira/browse/PIG-1782?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12988158#action_12988158
] 

Eric Yang commented on PIG-1782:
--------------------------------

@Bill, agree.  I filed a seperated jira for supporting timestamp.
@Dmitriy, Would it be possible to add a parameter to switch between the return type?

Suggested flags:
- -returnMap (default)
- -returnTuple

Example for Map:

{noformat}
CpuMetrics = load 'hbase://SystemMetrics' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('cpu:','-loadKey');
{noformat}

Example for Tuple:

{noformat}
CpuMetrics = load 'hbase://SystemMetrics' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('cpu:','-loadKey
-returnTuple');
{noformat}

> It would be nice to load all columns in the column family by using short hand syntax
like:
> {noformat}
> CpuMetrics = load 'hbase://SystemMetrics' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage('cpu:','-loadKey');
> {noformat}
> Assuming there are columns cpu: sys.0, cpu:sys.1, cpu:user.0, cpu:user.1,  in cpu column
family.
> CpuMetrics would contain something like:
> {noformat}
> (rowKey, cpu:sys.0, cpu:sys.1, cpu:user.0, cpu:user.1)
> {noformat}
