[jira] [Created] (HDFS-16859) acquirePermit : move LOG.debug into if condition

ZhangHB created HDFS-16859:
------------------------------

             Summary: acquirePermit : move LOG.debug into if condition
                 Key: HDFS-16859
                 URL: https://issues.apache.org/jira/browse/HDFS-16859
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: rbf
    Affects Versions: 3.3.4
            Reporter: ZhangHB


The invoke frequency of method AbstractRouterRpcFairnessPolicyController#acquirePermit is high.  before getting the permit of a nameservice, there is always a LOG.debug statement.

It is better to move the statement into if condition statement.
