> Most of the TimelineService HBase tables is set with username splits which is 
> based on lowercase alphabet (a,ad,an,b,ca,,,,). This won't help if the rowkey 
> starts with either number or uppercase alphabet. We need to allow user to 
> configure based upon their data. For example, say a user has configured the 
> yarn.resourcemanager.cluster-id to be ATS or 123, then the splits can be 
> configured as A,B,C,,, or 100,200,300,,,
