Ted Yu commented on HBASE-4345:
-------------------------------

Minor comment:
{code}
+    @Override
+    public boolean hasFilterRow() {
+      if (existingFilter == null)
+        return false;
+      else
+        return existingFilter.hasFilterRow();
+    }
{code}
else is not needed above.

What's the plan for all the sub-tasks of HBASE-2856 ?

> Ensure that Scanners that read from the storefiles respect MVCC

> Currently, the key-values written to the disk do not include the MVCC (RWCC) 
> version information. Once we add that
> information, and make it persistent to disk; let us make the scanners respect 
> the MVCC mechanism by ignoring 
> "newer" writes.
