Anoop Sam John commented on HDFS-9411: -------------------------------------- Guys .. Whether this is still active? We talked recently with one HDFS/HBase user and they also in need of a similar mechanism. We were thinking of using the favored nodes feature.. But the block re replication wont consider/honor this favored nodes (?) cc [~ram_krish], [~rakeshr] > HDFS NodeLabel support > ---------------------- > > Key: HDFS-9411 > URL: https://issues.apache.org/jira/browse/HDFS-9411 > Project: Hadoop HDFS > Issue Type: New Feature > Reporter: Vinayakumar B > Assignee: Vinayakumar B > Attachments: HDFSNodeLabels-15-09-2016.pdf, > HDFSNodeLabels-20-06-2016.pdf, HDFS_ZoneLabels-16112015.pdf > > > HDFS currently stores data blocks on different datanodes chosen by > BlockPlacement Policy. These datanodes are random within the > scope(local-rack/different-rack/nodegroup) of network topology. > In Multi-tenant (Tenant can be user/service) scenario, blocks of any tenant > can be on any datanodes. > Based on applications of different tenant, sometimes datanode might get busy > making the other tenant's application to slow down. It would be better if > admin's have a provision to logically divide the cluster among multi-tenants. > NodeLabels adds more options to user to specify constraints to select > specific nodes with specific requirements. > High level design doc to follow soon. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
