[jira] Commented: (CHUKWA-128) Tools to recompute aggregation

    [ https://issues.apache.org/jira/browse/CHUKWA-128?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699823#action_12699823 ] 

Cheng commented on CHUKWA-128:
------------------------------

In main method, if args.length < 4, variable endTime will equal 0. Since startTime is set to 0. the while loop block will be executed once. Is it expected behavior?

> Aggregation has dependency of running aggregation relative to the current time.  We need a set of tools to create partition and compute SQL aggregation manually.
