Namenode not starting

I'm trying to setup a hadoop cluster. But the namenode isn't starting. When i check the logs, it shows :

2016-10-19 05:23:10,140 FATAL org.apache.hadoop.hdfs.server.namenode.

/************************************************************

SHUTDOWN_MSG: Shutting down NameNode at namenode1/192.168.100.101

I've checked the core-site.xml file and found no errors.

<configuration>

<property>
<name>fs.default.name</name>
<value>192.168.100.101:9001</value>
</property>
</configuration>

I've also tried deleting the temp folder, formatting the namenode and starting it again.

1) Replace value of fs.default.name with hdfs://192.168.100.101:9001

2) Check your site.xml files, whether in value you have mistakenly added space in between
