org.apache.pig.experimental.logical.relational.LogicalSchema.findField()

Look for the index of the field that contains the specified uid @param uid the uid to look for @return the index of the field, -1 if not found

                return false;
            }
            
            Set<Integer> cols = new HashSet<Integer>();
            for(long uid: output) {
                int col = s.findField(uid);
                if (col < 0) {
                    throw new RuntimeException("Uid " + uid + " is not in the schema of " + op.getName());
                }
                cols.add(col);
            }

                             input.add(fuid);
                         }

                                 found = true;
                                 break;
                             }

                                uids.add(uid);
                            }
                        }
                    }
                }
