Resolution: Not A Problem
I have double checked again and found that there are some bugs in my local
branch but not in the master branch so I close this JIRA.

> Key: IMPALA-9746
> URL: https://issues.apache.org/jira/browse/IMPALA-9746
> Project: IMPALA
> Issue Type: Bug
> Reporter: Fang-Yu Rao
> Priority: Major
>
> Some masking options would result in IllegalStateException.
> For example, in Ranger's web UI, if we create a column masking policy with
> the Select Masking Option of "Hash", we will encounter an
> {{IllegalStateException}}. To create a column masking policy that masks the
> column via a hash function, currently a user has to create a column masking
> policy with Select Masking Option of "Custom" and expression equal to
> "mask_hash({col})". There are similar problems for the Select Masking Options
> of "Partial mask: show last 4" and "Date: show only year" as well.
> It would be easier for a user to just select a desired masking option
> described above instead of having to create a custom masking option and fill
> out the expression manually.
