---------------------------
Resolution: Won't Fix
> [SQL] SHOW FUNCTIONS did not work properly
> ------------------------------------------
>
> Key: SPARK-14323
> URL: https://issues.apache.org/jira/browse/SPARK-14323
> Project: Spark
> Issue Type: Bug
> Reporter: Bo Meng
> Priority: Minor
>
> Show Functions syntax can be found here:
> https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-ShowFunctions
> When use "*" in the LIKE clause, it will not return the expected results.
> This is because "\*" did not get escaped before passing to the regex. If we
> do not escape "\*", for example, pattern "\*f\*", it will cause exception
> (PatternSyntaxException, Dangling meta character) and thus return empty
> result.
> try this:
> val p = "\*f\*".r
