[jira] [Updated] (HIVE-5679) add date support to metastore JDO/SQL

     [ https://issues.apache.org/jira/browse/HIVE-5679?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

    Attachment: HIVE-5679.patch

Ok, this adds support, but only for actual date literals, comparing date column with valid date string value won't work so far.
I wasted a lot of time trying to make it work in Filter.g, and I cannot seemingly make the lexer go back to StringLiteral when it fails to validate invalid date string as date literal. Maybe someone with better Antlr skills can make this work (I also asked on SO). We can add a hack where, upon seeing date col and string value in metastore code, we will try to extract date once.
