Subject [jira] [Created] (CHUKWA-648) Make Chukwa Reduce Type to support hierarchy format
Date Mon, 16 Jul 2012 09:17:33 GMT
Jie Huang created CHUKWA-648:
--------------------------------

             Summary: Make Chukwa Reduce Type to support hierarchy format
                 Key: CHUKWA-648
                 URL: https://issues.apache.org/jira/browse/CHUKWA-648
             Project: Chukwa
          Issue Type: New Feature
          Components: Data Processors
    Affects Versions: 0.4.0, 0.6.0
            Reporter: Jie Huang


Currently the Reduce Type decides the final directory-structure of the processed data over
HDFS. And it doesn't support a hierarchy format like 
{noformat}
hdfs/namenode
hdfs/datanode
...
{noformat}
A hierarchy structure makes it easy to do the HDFS File Filter versus to the flat storage
structure while doing the analysis job.
