[jira] [Updated] (HIVE-5134) add tests to partition filter JDO pushdown for like and make sure it works, or remove it

["Sergey Shelukhin (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-5134?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Sergey Shelukhin updated HIVE-5134:
-----------------------------------

    Attachment: HIVE-5134-does-not-work.patch

Here's an example test (with some implementation), on top of HIVE-4914, that is not going to work.

If I remove the custom implementation and switch to UDFLike::likePatternToRegExp (moved into common to access from metastore), even fewer patterns from this test work.

We should be able to add this test and make it work in some way, or remove the code.

> There's a mailing list thread. Partition filtering w/JDO pushdown using LIKE is not used by Hive due to client check (in PartitionPruner); after enabling it seems to be broken. We need to fix and enable it, or remove it.
