----------------------------------------------------
Key: HDFS-1998
URL: https://issues.apache.org/jira/browse/HDFS-1998
Project: Hadoop HDFS
Issue Type: Bug
Components: scripts
Affects Versions: 0.23.0
Reporter: Tanping Wang
Assignee: Tanping Wang
Priority: Minor
Fix For: 0.23.0
refresh-namenodes.sh is used to refresh name nodes in the cluster to check for
updates of include/exclude list. It is used when decommissioning or adding a
data node. Currently it only refreshes the name node who serves the defaultFs,
if there is defaultFs defined. Fix it by refreshing all the name nodes in the
cluster.
