Description

The following log is displayed in every hdfs command when using DNSDomainNameResolver.

-bash-4.2$ hadoop fs -ls /
19/07/25 14:32:28 INFO ha.AbstractNNFailoverProxyProvider: Namenode domain name will be resolved with org.apache.hadoop.net.DNSDomainNameResolver
(snip)

Can we change the log level from info to debug?
