Gopal V created HIVE-21229: ------------------------------ Summary: Tez: Provide a Node-Label split affinity provider Key: HIVE-21229 URL: https://issues.apache.org/jira/browse/HIVE-21229 Project: Hive Issue Type: Bug Reporter: Gopal V
When the queue has node-labels, the delays involved in waiting for node locality are a net-loss to the query. Asking for locality in a node which is not available to the current queue is slowing down YARN task allocations. Also specifically, for the 3-replica HDFS case, picking the replica that belongs within the node-label is more efficient than picking a non-available node & falling back to rack_local instead. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
