Not able to run(schedule) oozie example map reduce job || java.net.ConnectException

I am using Hadoop 2.6.0 and oozie 5.2.0 version. Trying to run example Map reduce job in oozie but getting below error.

hadoop1@ip-172-31-84-37:/usr/local/oozie-5.2.0/examples/target/examples/apps/map-reduce$ oozie job -oozie http://localhost:11000/oozie -config job.properties -run

error screenshot Not sure if I have to change any configurations. I tried giving public dns in job.properties file instead of localhost but still got the same error. Any help is appreciated.

Call From ip-172-31-84-37/172.31.84.37 to localhost:8020 seems to say that your Oozie server (on localhost) is not running HDFS on port 8020. Use the wiki page in the error to debug your network setup...

Assuming you have an external HDFS address, then fs.defaultFS in $HADOOP_CONF_DIR/core-site.xml needs updated with the correct address.
