How to set Hue Plugin for JobTracker on a different host

Question

Hi. Please help me with setting the Hue plugin. Earlier I had the JobTracker and the Hue Server on the same host so I set the plugin using the following command. 

$ cd /usr/lib/hue
$ cp desktop/libs/hadoop/java-lib/hue-plugins-*.jar /usr/lib/hadoop-0.20-mapreduce/lib

Now the JobTracker and Hue server are on different hosts. How do I set the plugin?

Answer 1

When the JobTracker and the Hue Server are on different hosts, you will have to scp the Hue plugins to the JobTracker host. To do this, open the mapred-site.xml file and add the below lines in it:

<property>
  <name>jobtracker.thrift.address</name>
  <value>0.0.0.0:9290</value>
</property>
<property>
  <name>mapred.jobtracker.plugins</name>
  <value>org.apache.hadoop.thriftfs.ThriftJobTrackerPlugin</value>
  <description>Comma-separated list of jobtracker plug-ins to be activated.</description>
</property>
