Tsz Wo (Nicholas), SZE commented on HDFS-3391:
----------------------------------------------

The patch looks good.  Some comments:

- All calls of invalidateBlocks.contains(..) have matchGenStamp == true.  How about remove matchGenStamp from the parameters?

- Remove the TODO below.
{code}
-    if(invalidateBlocks.contains(dn.getStorageID(), block)) {
+    if(invalidateBlocks.contains(dn.getStorageID(), block, true)) {
 /*  TODO: following assertion is incorrect, see HDFS-2668
 assert storedBlock.findDatanode(dn) < 0 : "Block " + block
         + " in recentInvalidatesSet should not appear in DN " + dn; */
{code}

- In LightWeightHashSet.getEqualElement(..), since the key will be cast to T, change the type to T and remove @SuppressWarnings("unchecked").  Then, we need to cast the key to T in contains(..).  Add @Override to contains(..).  Also, how about renaming getEqualElement to getElement?
