      Description

      HBase provides dynamic columns, but it is costly to do table scan to figure out all the columns at real time. For HICC to display all columns stored in HBase to web user interface, it would be better to cache the meta data in a small table. This jira is to implement a mapreduce job which scans for new columns for specified time ranges and deposit the column names into a chukwa meta data table.
