ramkrishna.s.vasudevan reassigned HBASE-23270: ---------------------------------------------- Assignee: Pradeep > Inter-cluster replication is unaware destination peer cluster's RSGroup to > push the WALEdits > -------------------------------------------------------------------------------------------- > > Key: HBASE-23270 > URL: https://issues.apache.org/jira/browse/HBASE-23270 > Project: HBase > Issue Type: Bug > Reporter: Pradeep > Assignee: Pradeep > Priority: Major > > In a source RSGroup enabled HBase cluster where replication is enabled to > another destination RSGroup enabled cluster, the replication stream of > List<WAL.Edit> go to any node in the destination cluster without the > awareness of RSGroup and then gets routed to appropriate node where the > region is hosted. This extra hop where the data is received and routed could > be of any node in the cluster and no restriction exists to select the node > within the same RSGroup. > Implications: RSGroup owner in the multi-tenant HBase cluster can see > performance and throughput deviations because of this unpredictability caused > by replication. > Potential fix: options: > a) Select a destination node having RSGroup awareness > b) Group the WAL.Edit list based on region and then by region-servers in > which the regions are assigned in the destination. Pass the list WAL.Edit > directly to the region-server to avoid extra intermediate hop in the > destination cluster during the replication process. -- This message was sent by Atlassian Jira (v8.3.4#803005)
