---------------------------------
Summary: considerLoad factor can be improved
Key: HDFS-9318
URL: https://issues.apache.org/jira/browse/HDFS-9318
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.6.0
Reporter: Kuhu Shukla
Assignee: Kuhu Shukla
Currently considerLoad avoids choosing nodes that are too active, so it helps
level the HDFS load across the cluster. Under normal conditions, this is
desired. However, when a cluster has a large percentage of nearly full nodes,
this can make it difficult to find good targets because the placement policy
wants to avoid the full nodes, but considerLoad wants to avoid the busy
less-full nodes.
