hfile should change how it reads from hdfs -- pread/seek+read -- dependent on 
recent history

                 Key: HBASE-1505
                 URL: https://issues.apache.org/jira/browse/HBASE-1505
             Project: Hadoop HBase
          Issue Type: Improvement
            Reporter: stack


hfile preads all the time at moment.  its good we do this when we want to up 
our random reads.  but apparently pread involves open socket, seek, read, close 
socket whereas seek+read could leave us aligned at next block to read and make 
for some savings.  hfile could have a short memory and change how it pulls from 
hdfs dependent on recent history.
