[jira] Commented: (CHUKWA-564) HBase output collector uses
incorrect column family
[ https://issues.apache.org/jira/browse/CHUKWA-564?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12970084#action_12970084 ]
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.

> Key: CHUKWA-564
> URL: https://issues.apache.org/jira/browse/CHUKWA-564
> Project: Chukwa
> Issue Type: Bug
> Reporter: Bill Graham
> Fix For: 0.5.0
>
>
> 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.
