HBASE-26273 Force ReadType.STREAM when the user does not explicitly set a ReadType on the Scan for a Snapshot-based Job
HBase 2 moved over Scans to use PREAD by default instead of STREAM like
HBase 1. In the context of a MapReduce job, we can generally expect that
clients using the InputFormat (batch job) would be reading most of the
data for a job. Cater to them, but still give users who want PREAD the
ability to do so.
