---------------------------------------

             Summary: When there are unrecoverable ec block groups, Namenode Web UI shows "There are X missing blocks." but doesn't show the block names.
                 Key: HDFS-10827
                 URL: https://issues.apache.org/jira/browse/HDFS-10827
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Takanobu Asanuma
            Assignee: Takanobu Asanuma


For RS-6-3, when there is one ec block group and
1) 0~3 of 9 internal blocks are missing, NN Web UI doesn't show any warns.
2) 4~8 of 9 internal blocks are missing, NN Web UI shows "There are 1 missing blocks." but doesn't show the block names.
3) 9 of 9 internal blocks are missing, NN Web UI shows "There are 1 missing blocks." and also shows the block name.

We should fix the case 2). I think NN Web UI should show the block names since the ec block group is unrecoverable.

The values come from JMX. "There are X missing blocks." is {{NumberOfMissingBlocks}} and the block names are {{CorruptFiles}}.
