Summary: DatanodeAdminManager Improvements
Key: HDFS-13167
URL: https://issues.apache.org/jira/browse/HDFS-13167
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs
Affects Versions: 3.0.0
Reporter: BELUGA BEHR
# Use Collection type Set instead of List for tracking nodes
# Fix logging statements that are erroneously appending variables instead of
using parameters
# Miscellaneous small improvements
As an example, the {{node}} variable is being appended to the string instead of
being passed as an argument to the {{trace}} method for variable substitution.
{code}
LOG.trace("stopDecommission: Node {} in {}, nothing to do." +
node, node.getAdminState());
{code}
