Subject [jira] Commented: (CHUKWA-564) HBase output collector uses incorrect column family
Date Fri, 10 Dec 2010 06:08:00 GMT


Eric Yang commented on CHUKWA-564:

The current implementation of demux annotation has an issue to support multiple columnFamilies.
A demux parser could be writing out data to different column families.  I am having difficulty
to design a elegant annotation for supporting multi-column family demux parser while having
this work in map/reduce framework as well.  I am open to suggestions.

> The HBase {{OutputCollector}} does this to obtain the column family from the data type:
> {noformat}
> cf = key.getReduceType().getBytes();
> {noformat}
> The column family should instead be taken by the {{@Table.columnFamily}} annotation on
the processor.
