[jira] [Created] (HDFS-9443) Disabling HDFS client socket cache causes logging message printed to console for CLI commands.

-----------------------------------

             Summary: Disabling HDFS client socket cache causes logging message printed to console for CLI commands.
                 Key: HDFS-9443
                 URL: https://issues.apache.org/jira/browse/HDFS-9443
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth
            Priority: Trivial


The HDFS client's socket cache can be disabled by setting {{dfs.client.socketcache.capacity}} to {{0}}.  When this is done, the {{PeerCache}} class logs an info-level message stating that the cache is disabled.  This message is getting printed to the console for CLI commands, which disrupts CLI output.  This issue proposes to downgrade to debug-level logging for this message.
