Chukwa HBase storage should scan for column from most recent time instead of starting time
------------------------------------------------------------------------------------------

                 Key: CHUKWA-596
                 URL: https://issues.apache.org/jira/browse/CHUKWA-596
             Project: Chukwa
          Issue Type: Improvement
          Components: User Interface
    Affects Versions: 0.5.0
         Environment: Java 6, Mac OS X
            Reporter: Eric Yang
            Assignee: Eric Yang
             Fix For: 0.5.0


HICC UI access REST API with a time range.  i.e. Last 24 hours.  Current ChukwaHBaseStore
API is scanning for column names from start time to end time.  With full scan disabled, then
it is fetching a single row from the starting time to present the columns existed for that
time period.  Columne name retrieval does not work very well for cluster that has just been
setup because there is no data in the specified start time, but there is often data for specified
end time.  I recommend to change the column name retrieval api to use end time as indicator.
