Ted Yu commented on HBASE-16213:
--------------------------------

Lijin:
Can you add unit tests for ROW_INDEX_V1 ?

In the comparison, both key and value are 10B in size.
Can you perform comparison on larger key / values ?

> HFileBlock store cells sequential, current when to get a row from the block, it scan

> The new structure store every row's start offset with data, so it can find the exact
row with binarySearch.
