> The only way to find the error was to look at the javacc generated QueryParser.java code and do a System.out.println()
> Here is a script to reproduce the problem:
> {code}
> A = load '/user/viraj/three.txt' using PigStorage();
> B = foreach A generate ['a'#'12'] as b:map[] ;
> store B into '/user/secure/pigtest' using PigStorage();
> {code}
> "three.txt" has 3 lines which contain nothing but the number "1".
> {code}
> $ hadoop fs -ls /user/secure/
> ls: could not get get listing for 'hdfs://mynamenode/user/secure' : org.apache.hadoop.security.AccessControlException: Permission denied: user=viraj, access=READ_EXECUTE, inode="secure":secure:users:rwx------
> {code}
