Subject [jira] [Commented] (HDFS-9070) Erasure coding: allow fsck display the pending replica information(including datanode information) of being-written EC block group
Date Fri, 18 Sep 2015 16:55:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14875944#comment-14875944

Jing Zhao commented on HDFS-9070:
---------------------------------

Thanks for working on this, Rui! The patch looks good to me in general. Some comments:
# The change is not specific for EC files. We should do it in trunk directly.
# Looks like we should show expected locations of a under-construction block only when "showLocations"
is enabled?
# It's better to append the information to the {{report}} instead of directly using {{out.println}}.

> When a EC file is being written, it can be helpful to allow fsck display datanode information
of the being-written EC file block group.
