Subject [jira] [Updated] (HDFS-7916) 'reportBadBlocks' from datanodes to standby Node BPServiceActor goes for infinite loop
Date Wed, 12 Aug 2015 01:28:46 GMT

     [ https://issues.apache.org/jira/browse/HDFS-7916?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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.
