> Hedged reads came in in hadoop-2.4. hbase-2.0.0 requires a later version so we can expect
support to be preseent. This issue is about a bit of testing to show defined benefit when
hedged reads are on and then enabling them by default in hbase-2.0.0.
> See http://hbase.apache.org/book.html#_hedged_reads for current state of the doc.
> This issue came up in conversation a few of us were having Thursday and then Lars George
started asking me their state in the last 24 hours.
> Assigning myself to do the bit of testing and enabling.
