マルチノードハープループクラスタセットアップでデータノードを実行できませんでした。提案が必要

Question

マルチノードハープクラスタをセットアップしようとしていますが、データノードの起動に失敗しました。以下はその詳細です。これ以外の設定はありません。私は今のところ、データノードと名前ノードの設定が1つしかありません。

NAMENODE setup - 
CORE-SITE.xml 
<property> 
    <name>fs.defult.name</name> 
    <value>hdfs://192.168.1.7:9000</value> 
</property> 

HDFS-SITE.XML 

<property> 
    <name>dfs.name.dir</name> 
    <value>/data/namenode</value> 
</property> 




DATANODE SETUP: 

NAMENODE setup - 
CORE-SITE.xml 
<property> 
    <name>fs.defult.name</name> 
    <value>hdfs://192.168.1.7:9000</value> 
</property> 

HDFS-SITE.XML 

<property> 
    <name>dfs.data.dir</name> 
    <value>/data/datanode</value> 
</property> 

When I run namenode it runs fine however when I try to run data node on other machine whos IP is 192.168.1.8 it fails and log says

@   

and datanode dies 
Is anything there to setup ? 
let me any other details required. Is there any other files to change? I am using centos7 to setup the env. I did formatting of namenode also more than 2-3 times, and also permissions are proper. Only connectivity issue however when I try to scp from master to slave (namenode to datanode) its works fine. 
Suggest if there are any other setup to be done to make it successful!

設定のプロパティ名にタイプミスがあります。 'a'はありません：fs.defult.name（対fs.default.name）。
