stack commented on HBASE-17787:
-------------------------------

Unscheduling from 2.x. We depend on rollback. Needs beefing up as a notion. 
Currently anemic. Unscheduling as not important for 2.0.

> Drop rollback for all procedures; not useful afterall

> "Looking back rollback support is not really useful in our operations. We are 
> always able to complete the operation at some point. So stuff like create, 
> modify table, and so on. Should try to finish the operation instead of giving 
> up and rollback in case of failure (e.g. hdfs hiccup)"
