Wellington Chevreuil updated HBASE-21406: ----------------------------------------- Attachment: Screen Shot 2018-10-31 at 18.12.54.png > "status 'replication'" should not show SINK if the cluster does not act as > sink > ------------------------------------------------------------------------------- > > Key: HBASE-21406 > URL: https://issues.apache.org/jira/browse/HBASE-21406 > Project: HBase > Issue Type: Improvement > Reporter: Daisuke Kobayashi > Assignee: Wellington Chevreuil > Priority: Minor > Attachments: Screen Shot 2018-10-31 at 18.12.54.png > > > When replicating in 1 way, from source to target, {{status 'replication'}} on > source always dumps SINK with meaningless metrics. It only makes sense when > running the command on target cluster. > {{status 'replication'}} on source, for example. {{AgeOfLastAppliedOp}} is > always zero and {{TimeStampsOfLastAppliedOp}} does not get updated from the > time the RS started since it's not acting as sink. > {noformat} > source-1.com > SOURCE: PeerID=1, AgeOfLastShippedOp=0, SizeOfLogQueue=0, > TimeStampsOfLastShippedOp=Mon Oct 29 23:44:14 PDT 2018, Replication Lag=0 > SINK : AgeOfLastAppliedOp=0, TimeStampsOfLastAppliedOp=Thu Oct 25 > 23:56:53 PDT 2018 > {noformat} > {{status 'replication'}} on target works as expected.
