Takanobu Asanuma created HDFS-10827:
---------------------------------------
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}}.
