----------------------------------
Related to work on HIVE-4055. I'll do this fix as an additional item after
getting 4055 in.
> Date literals do not work properly in partition spec clause
> -----------------------------------------------------------
>
> Key: HIVE-4928
> URL: https://issues.apache.org/jira/browse/HIVE-4928
> Project: Hive
> Issue Type: Bug
> Components: Query Processor
> Reporter: Jason Dere
> Assignee: Jason Dere
>
> The partition spec parsing doesn't do any actual real evaluation of the
> values in the partition spec, instead just taking the text value of the
> ASTNode representing the partition value. This works fine for string/numeric
> literals (expression tree below):
> (TOK_PARTVAL region 99)
> But not for Date literals which are of form DATE 'yyyy-mm-dd' (expression
> tree below:
> (TOK_DATELITERAL '1999-12-31')
> In this case the parser/analyzer uses "TOK_DATELITERAL" as the partition
> column value, when it should really get value of the child of the DATELITERAL
> token.
