> The two delimiters passed to the 'str_to_map' function are both interpreted as regular expressions, which means that using the pipe ('|') as a delimiter will lead to very unexpected results.
> This behaviour is the same for the closely related 'split' function, however that is clearly documented in the function description (as per https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF). 
> Either the documentation for 'str_to_map' should be updated to reflect that the delimiters are both regular expressions, too, or the implementation should be changed to not interpret them as regexes.
