> Three common errors that occur during execution are:
> 1. Map-side group-by causing an out of memory exception due to large aggregation hash
tables
> 2. ScriptOperator failing due to the user's script throwing an exception or otherwise
returning a non-zero error code
> 3. Incorrectly specifying the join order of small and large tables, causing the large
table to be loaded into memory and producing an out of memory exception.
> These errors are typically discovered by manually examining the error log files of the
failed task. This task proposes to create a feature that would automatically read the error
logs and output a probable cause and solution to the command line.
