Subject [jira] [Commented] (ACCUMULO-3807) Log Recovery Copy/Sort progress exceeds 100%
Date Thu, 14 May 2015 22:18:31 GMT


Ed Coleman commented on ACCUMULO-3807:

I agree with [~ctubbsii] having progress sit at %100 is worse than a moving indicator with
funny looking numbers. 

Having numbers > than 100% does look odd, but as long as it is moving it reflects that
recovery is working and will eventually (hopefully) complete.

If it was clamped at 100% and then hung for any significant amount of time (maybe > 30
seconds), well I'm likely to start to panic that something else is wrong with the system.
First, something happened that caused log recovery, and now log recovery is hanging....

With 1.4.x versions I seem to recall recovery taking minutes in "bad" cases.  If the recovery
indicator was at 100% for that amount of time it would certainly cause me concern.

Maybe instead of a %, the number shown is # copy / sort operations?  While it would be nice
to know about how long things were going to take, if it can be estimated - otherwise it seems
more important to provide feedback and reflect that things are still progressing - whatever
form that is.

100%. We should either
