[jira] [Created] (HDFS-15197) Change ObserverRetryOnActiveException log to debug

Chen Liang created HDFS-15197:
---------------------------------

             Summary: Change ObserverRetryOnActiveException log to debug
                 Key: HDFS-15197
                 URL: https://issues.apache.org/jira/browse/HDFS-15197
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs
            Reporter: Chen Liang
            Assignee: Chen Liang


Currently in ObserverReadProxyProvider, when a ObserverRetryOnActiveException happens, ObserverReadProxyProvider logs a message at INFO level. This can be a large volume of logs in some scenarios. For example, when some job tries to access lots of files that haven't been accessed for a long time, all these accesses may trigger atime updates, which led to ObserverRetryOnActiveException. We should change this log to DEBUG.
