Yuzhang QIU commented on KYLIN-3844:
------------------------------------

And for extensibility and robustness, Implementing a interface of extending an 
abstract class for hbaseMappingAdapter may be more appropriate rather then any 
class which contain static method 'initHBaseMapping(CubeDesc)' and 
'initMeasureReferenceToColumnFailyWithChecking(CubeDesc)'.

> some instruction about config 'kylin.metadata.hbasemapping-adapter'

> Hi team:
>     When someone want to self-define hbase column family mapping, they may 
> need to know how to config 'kylin.metadata.hbasemapping-adapter'.
>     Although tracing the code at CubeDesc:around 678 will show the usage of 
> this configuration, some official instruction in document may be better.
>     Just a small suggestion. :)
