Namenode start error

Question

While starting namenode i am getting below error, what should I change in core-site.xml:

FATAL org.apache.hadoop.mapred.JobTracker: java.lang.IllegalArgumentException: Does not contain a valid host:port authority: local

core-site.xml 

Answer 1

Seems like the content in core-site.xml file is not right. The content in this file should look something like this:

  <property>
  <name>fs.default.name</name>
  <value>hdfs://localhost:9000</value>    //Instead of localhost you need to use AWS private IP address
  </property>
