  This document describes the functional specification for the Error Handling feature in Pig.
  
+ 
  == Error types and mechanism to handle errors ==
+ 
  The [[#cookbook|cook book]] discusses the classification of errors within Pig and proposes a guideline for exceptions that are to be used by developers. A reclassification of the errors is presented below.
  
  === Frontend errors ===
-  . The front-end consists of multiple components - parser, type checker, optimizer, translators, etc. These errors usually occur at the client side before the execution begins in Hadoop. All the errors from these components can be categorized as front-end errors. Components that are part of the front end will throw specific exceptions that capture the context. For example, the parser throws a `ParseException`, the type checker will throw a `TypeCheckerException`, the optimizer will throw a `LogicalOptimizerException`, etc. A list of the exceptions thrown in the front-end are as follows.

For example, the parser throws a `ParseException`, the type checker will throw a `TypeCheckerException`, the optimizer will throw a `LogicalOptimizerException`, etc. A list of the exceptions thrown in the front-end are as follows.

-  1. `JobCreationException` Used for indicating errors during Map Reduce job creation

-  1. `LogicalToPhysicalTranslatorException` Used for indicating errors during logical plan to physical plan translation
+    1. `LogicalToPhysicalTranslatorException` Used for indicating errors during logical plan to physical plan translation
-  1. `MRCompilerException` Used for indicating errors during map reduce plan compilation from physical plan

  === Backend errors ===
-  . The execution pipeline, the operators that form the pipeline and the map reduce classes fall into the back-end. The errors that occur in the back-end are generally at run-time. Exceptions such as `ExecException` and `RunTimeException` fall into this category. These errors will be propagated to the user facing system and an appropriate error message indicating the source of the error will be displayed.

  === Internal errors ===
-  . Any error that is not reported via an explicit exception is indicative of a bug in the system. Such errors are flagged as internal errors and will be reported as possible bugs. Any non Hadoop backend error is a bug in Pig.

  While the aforementioned errors describe a developer's viewpoint of errors, the user is interested in the source of the errors. A classification of the source of errors is given below.
  
-  1. User Input - Sources of user input error are syntax error, semantic error, etc.
+    1. User Input - Sources of user input error are syntax error, semantic error, etc.
-  1. Bug - An internal error in the Pig code and not related to the user's input
+    2. Bug - An internal error in the Pig code and not related to the user's input
-  1. User Environment - The client side environment
+    3. User Environment - The client side environment
-  1. Remote Environment - The Hadoop execution environment
+    4. Remote Environment - The Hadoop execution environment
  
  == Error codes ==
+ 
  Error codes are categorized into ranges depending on the nature of the error. The following table indicates the ranges for the error types in Pig. Normally, errors due to user input and bugs in the software are not retriable. Errors due to the user environment and remote environment may be retriable based on the context. Error codes will be used for documentation to help users address common errors.
+ 
- ||'''Error type''' ||'''Range''' ||
+ || '''Error type'''    	|| '''Range''' ||
- ||User Input ||1000 - 1999 ||
+ || User Input          	|| 1000 - 1999 ||
- ||Bug ||2000 - 2999 ||
+ || Bug             	|| 2000 - 2999 ||
- ||User Environment (retriable) ||3000 - 3999 ||
+ || User Environment (retriable)    || 3000 - 3999 ||
- ||User Environment ||4000 - 4999 ||
+ || User Environment     || 4000 - 4999 ||
- ||Remote Environment (retriable) ||5000 - 5999 ||
+ || Remote Environment (retriable)  || 5000 - 5999 ||
- ||Remote Environment ||6000 - 6999 ||
+ || Remote Environment   || 6000 - 6999 ||
-

  Programmatic access via Java APIs can query if exceptions are retriable or not. For external processes that rely on the return code of the process, the table given below will indicate the status of the process execution. Front-end exceptions will result in failures as far the user is concerned. Hadoop's errors are  not retriable and return fatal error code (2) or partial failure code (3).
+ 
- ||'''Status''' ||'''Return Code''' ||
+ || '''Status'''      	|| '''Return Code''' ||
- ||Successful Execution ||0 ||
+ || Successful Execution	|| 0 ||
- ||Retriable error ||1 ||
+ || Retriable error      || 1 ||
- ||Fatal error ||2 ||
+ || Fatal error          || 2 ||
- ||Partial failure ||3 ||
+ || Partial failure      || 3 ||

  == Error message ==
+ 
  The format of the error message shown to the user will be as follows:
  
  '''ERROR <Error code>: <Error message>'''
@@ -68, +72 @@

  E.g.: ERROR 1005: The arity of the group by columns do not match.
  
  == Requirement on UDF authors ==
+ 
  In order to enable warning message aggregation, UDF authors should use Pig's abstraction to handle warning message aggregation. For more details refer to the [[#design|design document]].
  
  {{attachment:PigLogger.jpg}}
  
  === Warning Codes ===
+ 
- Each warning message will be associated with a warning code. The warning code will correspond to the enum type used for the warning message aggregation.

  == Additional command line switches ==
+ 
  In order to support the ability to turn on/off warning message aggregation, log error messages to client side logs and specify the location of the client side log, the following switches will be added to and/or extended in Pig.
  
-  1. -wagg to turn on warning aggregation; by default warning aggregation is turned off.

-  1. <<Anchor(clientSideLog)>>-l directory where the client side log is stored; by default, logs will be stored in the current working directory and named pig_<datestamp>.log. When used in batch mode (i.e., when a script to be executed is provided), the log file name will also contain the name of the script - pig_<datestam>_<pig_file>.log.

  == Compendium of error messages ==

  A list of possible error messages is listed below. This list is not comprehensive and will be modified to reflect the true error message along with the error code.
