> Looks like we are using seekTo() api in HfileScanner to seek to the key of
> interest. But under the hood, once the key is matched, the cursor is rewinded
> back to the starting of the data block.
> Ref:
> [https://github.com/apache/hbase/blob/cf02edbb1cea37a9a1cc4a64ff50f77a86955e5c/hbase-server/src/main/java/org/apache/hadoop/hbase/io/hfile/HFileScanner.java#L51]

> So, we want to fix the on-demand use-case to use reseek() apis which will
> leave the cursor as is.
