[jira] [Resolved] (HBASE-22762) Print the delta between phases in the split/merge/compact/flush transaction journals

["Andrew Purtell (JIRA)" <ji...@apache.org>]

Andrew Purtell resolved HBASE-22762.
------------------------------------
    Resolution: Fixed

Nothing to be done. Looks like under mt scenarios the logger only keeps a certain amount of buffer space free per thread and truncates overlong strings at their start. Might be fixable if we use something other than HRegion.LOG to log but no context to do that. Too much work for this change. Pushed addendum to branch-1.3, branch-1.4 and branch-1

> 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.
