Question

• I am trying to setup my Eclipse for Hadoop using this page
• I am using hadoop eclipse plugin jar from here
• my core-site.xml looks like has the following:

  <property>
  <name>fs.default.name</name>
  <value>hdfs://localhost:54310</value>
  <description>The name of the default file system.  A URI whose
  scheme and authority determine the FileSystem implementation.  The
  uri's scheme determines the config property (fs.SCHEME.impl) naming
  the FileSystem implementation class.  The uri's authority is used to
  determine the host, port, etc. for a filesystem.</description>
</property>
</configuration>

• my mapred-site.xml has following

<property>
  <name>mapred.job.tracker</name>
  <value>localhost:54311</value>
  <description>The host and port that the MapReduce job tracker runs
  at.  If "local", then jobs are run in-process as a single map
  and reduce task.
  </description>
</property>

• I set up hadoop location under mapreduce perspective in Eclipse as

  Location Name: local Map Reduce Master

  • Host: localhost
  • port: 54310

  DFS Master

  • Host: localhost
  • port: 54311

• When I try to connect it gives error saying:

Error: Call to localhost/127.0.0.1:54311 failed on local exception: java.io.EOFException

• Can someone please help me to resolve this issue?

Unfortunately eclipse plugin is outdated, few months ago I managed to get it working properly, but that was a nightmare, I had to change a lot of parameters there : (

I would recommend to use a web based hdfs browsing: go to http://localhost:50070 or any other host you have installed hadoop, and click on “Browse the filesystem” link (the first blue link from above), you will see all you need.
