Summary: Balancer configures DN properties directly on-demand
Key: HDFS-10295
URL: https://issues.apache.org/jira/browse/HDFS-10295
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: 2.7.0
Reporter: John Zhuge
Assignee: John Zhuge
This is a further enhancement to HDFS-10294. Instead of using NN APIs, use new
DN APIs to query and set necessary properties on the DNs involved.
Details:
* Before each balancing iteration, set the properties on all DNs involved in
the current iteration.
* Need new DN APIs to query and set the balancing properties.
