Vinod Kumar Vavilapalli updated HDFS-7916:
------------------------------------------
    Labels:   (was: 2.6.1-candidate)

I earlier removed HDFS-7916 from the 2.6.1-candidate list given HDFS-7704 was 
only in 2.7.0.

[~ctrezzo] added it back and so it appeared in my lists. I removed the label 
again, Chris, please comment on the mailing lists as to why you added it back. 
If you want it included, please comment there and we can add it after we figure 
out the why and the dependent tickets.

> 'reportBadBlocks' from datanodes to standby Node BPServiceActor goes for
