Chia-Ping Tsai resolved HBASE-8028.
-----------------------------------
    Resolution: Won't Fix

We don't need the rollback in 2.0.0 after committing the HBASE-15158. The rollback for Append/Increment
in 1.x has been fixed by HBASE-17519.

> In case there is an exception while doing the log-sync, the memstore is not rollbacked,
while the mvcc is _always_ forwarded to the writeentry created at the beginning of the operation.
This may lead to scanners seeing results which are not synched to the fs.
