> When I look at fix of HDFS-4879, I noticed that class BlocksMapUpdateInfo in
> INode.java, has a constructor that still uses ArrayList<Block> (which
> HDFS-4879 tries to replace with ChunkedArrayList for better memory efficiency)
> {code}
> public static class BlocksMapUpdateInfo {
> ......
> public BlocksMapUpdateInfo(List<Block> toDeleteList) {
> this.toDeleteList = toDeleteList == null ? new ArrayList<Block>()
> : toDeleteList;
> }
> ......
> }
> {code}
> It turns out that this constructor is not used anywhere (thanks [~cmccabe]
> for pointing this out). I'm filing this JIRA to remove it.
