Not able to run dump in pig

I am trying to dump a relation but getting following error.

I have tried start-all.sh and tried formatting namenode using hadoop namenode -format.

But I am not getting what is wrong. 

Error:-
Already tried 9 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1000 MILLISECONDS)
Solution

  • Start the JobHistoryServer

    $HADOOP_HOME/sbin/mr-jobhistory-daemon.sh start historyserver

    Pig when ran in mapreduce mode expects the JobHistoryServer to be available.

    To configure JobHistoryServer, add these properties to mapred-site.xml replacing hostname with actual name of the host where the process is started

    <property>
   <name>mapreduce.jobhistory.address</name>
   <value>hostname:10020</value>
</property>
<property>
   <name>mapreduce.jobhistory.webapp.address</name>
   <value>hostname:19888</value>
</property>
