Description

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.
