I'm no expert, but could you use the regexp_replace or translate function?
>From the Hive wiki
<https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF#LanguageManualUDF-StringFunctions>
:
regexp_replace(string INITIAL_STRING, string PATTERN, string REPLACEMENT)
>
> Returns the string resulting from replacing all substrings in
> INITIAL_STRING that match the java regular expression syntax defined in
> PATTERN with instances of REPLACEMENT, e.g. regexp_replace("foobar",
> "oo|ar", "") returns 'fb.' Note that some care is necessary in using

> the letter s; '
> s' is necessary to match whitespace, etc.

translate(string input, string from, string to)
