Connection Error in Apache Pig
Yes the problem was that the job history server was not running.
All we had to do to fix this problem was enter this command into the command prompt:
mr-jobhistory-daemon.sh start historyserverThis command starts up the job history server. Now if we enter 'jps', we can see that the JobHistoryServer is running and my Pig jobs no longer waste time trying to connect to the server.
I think, this problem is related to hadoop mapred-site configuration issue. History Server runs default in localhost, so you need to add your configured host.
<property> <name>mapreduce.jobhistory.address</name> <value>host:port</value></property>then fire this command -
mr-jobhistory-daemon.sh start historyserver
I am using Hadoop 2.6.0, so I had to do
$ mr-jobhistory-daemon.sh --config /usr/local/hadoop/etc start historyserverwhere, /usr/local/hadoop/etc is my HADOOP_CONF_DIR.
