Change subject: IMPALA-6813: Hedged reads metrics broken when scanning non-HDFS 
based table
......................................................................


Patch Set 3: Code-Review+2

preads add some overhead to HDFS, since it sends out redundant read requests to 
replicas. Having it on by default might cause some confusion while running 
multiple heavy concurrent workloads.

Carry +2.
