[jira] [Created] (HDFS-17242) Make congestion backoff time configurable

farmmamba created HDFS-17242:
--------------------------------

             Summary: Make congestion backoff time configurable
                 Key: HDFS-17242
                 URL: https://issues.apache.org/jira/browse/HDFS-17242
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs-client
    Affects Versions: 3.4.0
            Reporter: farmmamba


Currently，if we enable congestion backoff, we will actually invoke backOffIfNecessary method. and the backoff time is computed using CONGESTION_BACKOFF_MEAN_TIME_IN_MS and CONGESTION_BACK_OFF_MAX_TIME_IN_MS which are hard-code. We should better make them configurable to compute backoff sleep time flexibly.
