HuangTao commented on HDFS-15140:
---------------------------------
about the patch, I find two points need to change
{code}
ReplicaInfo orig = b.getOriginalReplica();
- builders.get(volStorageID).add(orig);
+ unsortedBlocks.get(volStorageID).add(b); # replace b with orig
{code}
{code}
+ unsortedBlocks.put(
+ v.getStorageID(), new ArrayList<ReplicaInfo>(131072)); # should
use a constant variable
{code}
> Replace FoldedTreeSet in Datanode with SortedSet or TreeMap
