-----------------------------------------------
bq. The RDBStore and TypedTable can be responsible for the kv store manager, so
we can starts all work by the moving the code of RDBStore related to
hadoop-common, so that ozone and hdfs or yarn and other component can use this
wonderful feature without any more effort.
[~maobaolong], good idea (y).
