[GitHub] [hbase] jojochuang commented on pull request #3426: HBASE-26032 Make HRegion.getStores() an O(1) operation

   Ok I came up with a hack to maintain backward compat:
   
   We can retain the return type of getStores. For HRegion, it returns a special List subclass that behaves just like a Collection: pass the Collection object, delegate operations to it, and reject any List-only operation.
   
   There is no operation in the HBase code that must require performing List operations on the stores. If a coprocessor need List semantics, it can easily convert to a real list.
   
   See if you guys like this approach.
