[jira] Created: (HADOOP-5060) Create a generic aggregator for Chukwa

Create a generic aggregator for Chukwa
--------------------------------------

                 Key: HADOOP-5060
                 URL: https://issues.apache.org/jira/browse/HADOOP-5060
             Project: Hadoop Core
          Issue Type: New Feature
          Components: contrib/chukwa
            Reporter: Jerome Boulon


Create a generic way to compute aggregation on top of chukwaRecords based on a config file
Should be able:
- work on several Chukwa streams 
- To aggregate by time period
- Group by values for specific keys
- Provide a redefine list of functions (AVG,MIN,MAX,Counter->Rate conversion...)
- work with new functions

Jerome Boulon commented on HADOOP-5060:
---------------------------------------

Should be able to compute recursive aggregation in one pass based on the key:
ex: Aggregation Key = ABCD => ABC,AB, A should automatically be computed

Real AVG will be compute at the minute level, approximation will be done for 5,10,30, etc aggregation periods

---------------------------------------

Aggregation will be done using M/R and input data should be on HDFS, so not at the collector level.

[jira] Commented: (HADOOP-5060) Create a generic aggregator for Chukwa

Ari Rabkin commented on HADOOP-5060:
------------------------------------

There's substantial interest at Berkeley in doing some sort of in-collector aggregation, to get very short latencies.  It would be a big help if the code written for this JIRA were modular in such a way that it could be pulled out of the map-reduce framework, and run separately.   It's already pretty straightforward to extract Records in the collector.

------------------------------------

Clarification:

Is the idea to aggregate off HDFS, or do it at the collector?
