Solution

  • That's not "Job Configuration". It is whole cluster config.

    You can use cURL to parse it

    $ curl -s http://localhost:8088/conf | grep defaultFS
<property><name>fs.defaultFS</name><value>file:///</value><final>false</final><source>core-default.xml</source></property>
<property><name>mapreduce.job.hdfs-servers</name><value>${fs.defaultFS}</value><final>false</final><source>mapred-default.xml</source></property>
