Rajeshbabu Chintaguntla commented on HBASE-18446:
-------------------------------------------------
[~Apache9] [~anoop.hbase] We use LocalIndexStoreFileScanner,
IndexHalfStoreFileReader to implement HalfStoreFileReader functionality
supported after region split/merges. With HalfStoreFileReader we limit the
HFile scan to the child region boundary but with local index we need to do full
HFile scan and should be able to find the whether Cell belongs the child region
based on actual data row key. We use preStoreFileReaderOpen cp hook to create
the custom reader one time. Since the hook returns the reader we need to just
extend it instead of wrapping into some other class.
> Mark StoreFileScanner as IA.Private
