Timeout error when trying to connect to hadoop datanode

I'm getting this error when trying to putfile into hdfs.

org.apache.hadoop.net.ConnectTimeoutException: 60000 millis timeout while 
waiting for channel to be ready for connect. ch : 
java.nio.channels.SocketChannel[connection-pending remote=/10.1.1.14:50010]

I've looked up solutions and I see that you need to add this property to hdfs-site.xml:

<property>
  <name>dfs.client.use.datanode.hostname</name>
  <value>true</value>
</property>

I'm using ambari to manage my hadoop services. How to add the property without it resetting to defaults after I restart hdfs on ambari? I am on a single node cluster running HDP 2.6.1.0.

Update: Managed to add properties to hdfs-site.xml 

  <property>
      <name>dfs.datanode.use.datanode.hostname</name>
      <value>true</value>
  </property>


  <property>
      <name>dfs.client.use.datanode.hostname</name>
      <value>true</value>
    </property>

However, I am still getting the same Timeout error.

Use this in hdfs site xml

<property> 
   <name>dfs.namenode.name.dir</name> 
   <value>file:/path/to/hadoop/namenode</value> 
 </property> 

 <property> 
   <name>dfs.datanode.data.dir</name> 
   <value>file:/path/to/hadoop/datanode</value> 
 </property>
