Hi,
I have deployed Hadoop ecosystem using apache ambari. I am facing the same problem.
grunt> REGISTER piggybank.jar;
2014-09-23 16:49:03,880 [main] INFO org.apache.hadoop.conf.Configuration.deprecation – fs.default.name is deprecated. Instead, use fs.defaultFS
2014-09-23 16:49:03,919 [main] ERROR org.apache.pig.tools.grunt.Grunt – ERROR 101: file ‘piggybank.jar’ does not exist.
Details at logfile: /root/pig_1411471132022.log
I have checked /usr/lib/pig “piggybank.jar” does exist over there. Please advise.
