Ted Yu commented on HBASE-8028:
-------------------------------

For deleteKVWithMvccReadPoint():
{code}
+    while (iter.hasNext()) {
+      KeyValue cur = iter.next();
+      LOG.warn("kv present is: " + cur);
+      if (cur.matchingRow(referenceKV) && cur.matchingQualifier(referenceKV)) {
{code}
Can we utilize the following ?
http://docs.oracle.com/javase/6/docs/api/java/util/SortedSet.html#tailSet(E)
                
> 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.
