Correction: we seem to always write hbase checksums inline with the data.
The HBase checksums are always present.  The flag then is just about
whether they are used at read time.  If so, at read time, we ask for a
stream from HDFS that does not validate checksums (if an error on this
stream, we reopen asking HDFS to do checksum validation).
