Andrew Purtell commented on HBASE-22762:
----------------------------------------
Still working on the addendum.
Monitored task journal dump can get partially clobbered, looks like
multithreading issue on the logger not an issue with the patch. Looking at what
can be done without any significant change.
> Print the delta between phases in the split/merge/compact/flush transaction
> journals

> We print the start timestamp for each phase when logging the
> split/merge/compact/flush transaction journals and so when debugging an
> operator must do the math by hand. It would be trivial to also print the
> delta from the start timestamp of the previous phase and helpful to do so.
