Subject [jira] [Created] (KYLIN-3289) Refactor the storage garbage clean up code
Date Tue, 13 Mar 2018 01:56:00 GMT
Guangyao Li created KYLIN-3289:

             Summary: Refactor the storage garbage clean up code
                 Key: KYLIN-3289
             Project: Kylin
          Issue Type: Improvement
    Affects Versions: v2.3.0
            Reporter: Guangyao Li
             Fix For: v2.3.1

Kylin will produce some garbage data in storage when it runs.

Now, the clean up tool "{{ org.apache.kylin.tool.StorageCleanupJob}}" can show what
is garbage data or clean up the garbage by setting options "–delete false" or "delete true".

But Kylin can't show the size of garbage data for users.

This reconfiguration adds some member variables and methods recording the  garbage size
in the detection process. 

After clean up job running over, Kylin can get the information about garbage size.
