Ted Yu commented on HBASE-8028:
-------------------------------
{code}
+ if(oldKvs != null)
+ tempMemstoreWithOlderKVs.put(store, oldKvs);
{code}
Can CF version checking be done above so that we don't accumulate KeyValues
which would not be used in rollback ?
> Append, Increment don't handle wal-sync exceptions correctly

> 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.
