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.
