             Summary: Switch leftover logs to slf4j format in BlockManager.java
                 Key: HDFS-11832
                 URL: https://issues.apache.org/jira/browse/HDFS-11832
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: namenode
    Affects Versions: 3.0.0-alpha1, 2.8.0, 2.7.0
            Reporter: Hui Xu
            Priority: Minor


HDFS-7706 Switch BlockManager logging to use slf4j. But the logging formats were not changed appropriately. For example:
      if (LOG.isDebugEnabled()) {
        LOG.debug("blocks = " + java.util.Arrays.asList(blocks));
      }
These codes should be changed to:
      LOG.debug("blocks = {}", java.util.Arrays.asList(blocks));
