Improve data aggregation in database
------------------------------------
Key: HADOOP-4827
URL: https://issues.apache.org/jira/browse/HADOOP-4827
Project: Hadoop Core
Issue Type: Improvement
Components: contrib/chukwa
Environment: Redhat EL 5.1, Java 6
Reporter: Eric Yang
Assignee: Eric Yang
Chukwa is running data aggregation in database, and it has the ability to
generate SQL statements base on macros. On the other hand, there is also
Consolidator program which Chukwa uses to down sample data in the database.
Consolidator program can be replaced with the generic Aggregator program plus
some macros. This enhancement will make the database aggregation framework
cleaner.
