Hi, When I am trying to use the "explain" command, I am getting an error ERROR org.apache.pig.tools.grunt.GruntParser - java.lang.RuntimeException: java.io.IOException: Serialization error: org.apache.pig.impl.util.LineageTracer
The logical plan is getting displayed but while displaying the physical plan, this exception occurs. I am also getting an error while using "illustrate". The error is: ERROR org.apache.pig.tools.grunt.GruntParser - java.lang.ClassCastException: org.apache.pig.data.Tuple cannot be cast to org.apache.pig.data.ExampleTuple Pig Version - Pig 0.1.1 Hadoop Version - Hadoop 0.18.3 Could someone suggest what the issue could be? Regards, Padmashree
