Why TreeSet is used when collecting block information FSDataSet::getBlockReport
-------------------------------------------------------------------------------

                 Key: HDFS-1287
                 URL: https://issues.apache.org/jira/browse/HDFS-1287
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: NarayanaSwamy


As a return value we are converting this to array and returning and in name node also we are
iterating ... so can we use list onstead of set. (As the block ids are unique, there may not
be duplicates)
