----------------------------------------
[~larsh], The attached addendum patch run successfully on my local machine
except the following tests: MutableIndexIT.testCompoundIndexKey:372
expected:<y> but was:<null>
[ERROR] MutableIndexIT.testCompoundIndexKey:372 expected:<y> but was:<null>
[ERROR] MutableIndexIT.testMultipleUpdatesToSingleRow:502 expected:<y> but
was:<null>
[ERROR] MutableIndexIT.testMultipleUpdatesToSingleRow:502 expected:<y> but
was:<null>
I run them again and they passed. I pushed the patch to the master branch. I
will also push it the other branches too.

> Read repair (GlobalIndexChecker) sets the time range for the scan on the data
> table for using the timestamp of the index table row to be repaired. The
> start time for the scan is the timestamp of the index row in the current
> implementation. However, if the index row timestamp is higher than the data
> table row timestamp, then the data table row will not be visible to the scan.
> The index row timestamp can be higher when the index row is overwritten with
> the unverified row status (in the first write phase) but the data table row
> is not overwritten (in the second write phase) due to a failure. In this
> case, the unverified index row will not be rebuilt and will be deleted
> eventually.
