stack commented on HBASE-8322:
------------------------------

I am +1 on this.

Any chance of a warning log message if h1 and NOT short-circuit read also?  i.e. you may be
double-checksuming, see....

Good on you [~enis]

> Double checksumming issues in HBase level checksums(HBASE-5074) has been fixed in HBASE-6868.
However, that patch also disables hbase checksums by default. I think we should re-enable
it by default, and document the interaction with shortcircuit reads.
