-----------------------------
Summary: Support maintenance state for datanodes
Key: HDFS-7877
URL: https://issues.apache.org/jira/browse/HDFS-7877
Project: Hadoop HDFS
Issue Type: New Feature
Reporter: Ming Ma
This requirement came up during the design for HDFS-7541. Given this feature is
mostly independent of upgrade domain feature, it is better to track it under a
separate jira. The design and draft patch will be available soon.
