> After enabling HDFS HA, hdfs-site.xml does not include property  
> dfs.client.retry.policy.enabled and 'hdfs getconf -confKey 
> dfs.client.retry.policy.enabled' returns empty value. 
> The property dfs.client.retry.policy.enabled is important when HA is enabled, 
> as it enables HDFS client retry in case of NameNode failure. So, after 
> enabling HDFS HA, Ambari should set this property to true in hdfs-site.xml.
