Subject [jira] [Commented] (HDFS-8196) Erasure Coding related information on NameNode UI
Date Fri, 10 Feb 2017 13:47:41 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8196?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15861284#comment-15861284

Kai Sasaki commented on HDFS-8196:

[~tasanuma0829] Thanks for comments!
How about summarizing one row?
Looks good. I'll try.

We plan to implement EC + Contiguous in HDFS-8030. 
After contiguous block is implemented, we can add another field to show the metrics of the
ones. I think showing the metrics by block group type (striped, contiguous) is helpful. But
if {{fsck}} shows two type of block group metrics as one field, we can consolidate them as
{{Erasure-Coded}} metrics as you said.
