Rakesh R resolved HDFS-3854. ---------------------------- Resolution: Duplicate > Implement a fence method which should fence the BK shared storage. > ------------------------------------------------------------------ > > Key: HDFS-3854 > URL: https://issues.apache.org/jira/browse/HDFS-3854 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: namenode > Reporter: Uma Maheswara Rao G > Assignee: Rakesh R > > Currently when machine down or network down, SSHFence can not ensure that, > other node is completely down. So, fence will fail and switch will not happen. > [ internally we did work around to return true when machine is not reachable, > as BKJM already has fencing] > It may be good idea to implement a fence method, which should ensure shared > storage fenced propertly and return true. > We can plug in this new method in ZKFC fence methods. > only pain points what I can see is, we may have to put the BKJM jar in ZKFC > lib for running this fence method. > thoughts? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
