org.apache.pig.newplan.logical.rules.LoadStoreFuncDupSignatureValidator
Check for duplicate alias. This is because we use alias as LoadFunc signature. If user use the same alias in two load statement, we cannot distinguish two loadFunc. LoadStoreFuncDupSignatureValidator solve this problem by appending an index if signature conflicts
