Anoop Sam John commented on HBASE-12116:
----------------------------------------

On the TRT patch
For the 1st time call on includeTimestamp () we need set the minimumTimestamp and maximumTimestamp
to the give ts no?
If the includeTimestamp () call happens in a decreasing ts way you can see the min value will
get changed all the time and the max will never change and be at -1 always !
