can anybody help me to resolve this?
The code:
data = LOAD '/home/biadmin/PIGData/books.csv';
b = FOREACH data GENERATE $0;
DUMP b;

Answer 1

Based on the above exception , the input file is not there in the given path file:/home/biadmin/PIGData/books.csv. (which is local file system path)
Pig has two execution modes:
1. local mode (To process local file system files)
$ pig -x local
2. Mapreduce mode (To process HDFS file system files)
$ pig or $ pig -x mapreduce
Make sure that you are running the pig script in appropriate mode.
