Vinayakumar B commented on HDFS-10838:
--------------------------------------
Changes looks fine to me,
Was having one doubt about the compatibility of {{dfsadmin -report}} output.
[~aw], Can you confirm addition of new line {{"Last Block Report: ").append(new
Date(lastBlockReportTime))}} for each DN , whether this will be incompatible
change? Asking this doubt, because its a new addition in separate line. No
modifications to existing output lines.
> Last full block report received time for each DN should be easily discoverable
