Subject [jira] [Commented] (CHUKWA-674) Integrate Chukwa collector feature to Chukwa agent
Date Sat, 08 Dec 2012 17:41:21 GMT

Eric Yang commented on CHUKWA-674:
----------------------------------

Hi Shreyas, the connector interface is for configuration setup, and connections setup.  HBase
connector has different logic than http connector because the mechanism to talk to the destination
nodes are different.  It is possible that there is no HBaseSender.send() in HBase connector.
 Chukwa agent should be modified to use ChukwaWriter as default.  CollectorWriter would host
the logic of httpConnector.  EventQueue is only created for httpConnector.  ChukwaWriter uses
the add(List<Chunk>) to push data out instead.

> Feature offered in Chukwa collector can be integrated into Chukwa agent, and use multi-tier
Chukwa agent to collect data for large scale cluster.  For small cluster, agents can talk
directly to HDFS cluster to reduce the complexity of deployment.  The required features to
reduce the need of Chukwa collectors are: 
> - Enhance agent rest api to receive chunk data.
> - Pipeline writer to channel data to storage destinations (HDFS, HBASE).
> - Improve connector interface and replace http connector with collector connector for
bandwidth balance.
