The HBase client scanner goes through the regions in the scan range one at
a time, making call to the region server.
See this pending JIRA for the relevant discussion.

Does hbase scan or get is single threaded?
Say I have hbase table with 100 regionservers.
When I scan a key rangle say a-z(distributed on all regionservers), will
the client make calls to regionservers in parallel all at once or one by
one.First it will get all keys from one regionserver then
