Currently Timeline Service Storage tables uses splits based on username.
ApplicationTable rowkey starts with ClusterId, AppToFlowTable rowkey starts
with AppId won;t work well with username splits. The Hbase write will hotspot
to one RegionServer. Need to optimize the pre split keys for each tables based
on the RowKey.
