-----------------------------------

             Summary: Rename parameters related to counters / memory distribution
                 Key: TEZ-1674
                 URL: https://issues.apache.org/jira/browse/TEZ-1674
             Project: Apache Tez
          Issue Type: Improvement
            Reporter: Siddharth Seth
            Assignee: Siddharth Seth
            Priority: Critical


The parameter names don't make a lot of sense right now, or duplicate information.

Previous name   Current name after the 0.5 refactor.
tez.runtime.job.counters.max  tez.am.counters.max.keys
tez.runtime.job.counters.group.name.max tez.am.counters.group-name.max.keys
tez.runtime.job.counters.counter.name.max tez.am.counters.name.max.keys
tez.runtime.job.counters.groups.max tez.am.counters.groups.max.keys
A lot of these are not related to keys

tez.task.scale.memory.allocator.class tez.task.scale.task.memory.allocator.class
tez.task.scale.memory.reserve-fraction  tez.task.scale.task.memory.reserve-fraction
tez.task.scale.memory.additional.reservation.fraction.per-io  tez.task.scale.task.memory.additional-reservation.fraction.per-io
tez.task.scale.memory.additional reservation.fraction.max tez.task.scale.task.memory.additional-reservation.fraction.max
tez.task.initial.memory.scale.ratios  tez.task.scale.task.memory.ratios
task is duplicated

Also
tez.task.max-events-per-heartbeat.max - repeats max

I'd prefer to have made these changes directly, but after talking to [~hitesh], will add deprecation - and target removal in 0.7
