Issue: Eclipse Hadoop plugin issue(Call to localhost/127.0.0.1:50070 failed on local exception: java.io.EOFException). Can any body give me the solution for this?
I am having Cloudera training tutorial. Which uses Eclipse(Helios)3.6 and Hadoop.0.20.2-cdh3u2 versions.
I had downloaded the hadoop-eclipse-plugin-0.20.3-SNAPSHOT.jar and copied the same in /home/training/eclipse/plugins/ folder.
Run --> Eclipse --> gone to File (which is in Menu bar) --> New --> other
From other Selected the MapReduce Project. I had selected the Specify Hadoop library location. And given location as "/usr/lib/hadoop". In this location I have below files.
bin hadoop-examples-0.20.2-cdh3u2.jar
build.xml hadoop-examples.jar
CHANGES.txt hadoop-test-0.20.2-cdh3u2.jar
conf hadoop-test.jar
contrib hadoop-tools-0.20.2-cdh3u2.jar

and given the Mpareduce Project as "myhadoop" and clicked the finish button. I got the Mapreduce button at DFS Locations button and but not its hirearchy.
Gone and checked my dfs and mapred ports.
My core-site.xml is
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:8020</value>
</property>
my mapred-site.xml
<configuration>
<property>
<name>mapred.job.tracker</name>
<value>localhost:8021</value>
</property>
At Map ReTo Define Hadoop Location in eclipse I had given as below.
Map/Reduce Master
Host: localhost
port 50021
DFS Master:
Host :localhost
Port:50020
at the same I am select use M/R host.
I had ran cloudera's example wordcount program but it is giving me below issue. Please give me solution I am trying from 2 days.,....
