                 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}
