> 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.
