[jira] [Updated] (HIVE-5342) Remove pre hadoop-0.20.0 related codes

     [ https://issues.apache.org/jira/browse/HIVE-5342?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ashutosh Chauhan updated HIVE-5342:
-----------------------------------

    Status: Open  (was: Patch Available)

* In SkewJoinHandler, you can get rid of catch(IOException) block altogether.
* In LazySimpleSerde::deserialize() lets not do any instanceof check. Since this is on performance critical path, we should avoid any if branch. Lets just cast it to BinaryComparable. In worst case, ClasscastException would be thrown, which is fine.
* Same as above for LazyBinarySerde.

> Remove pre hadoop-0.20.0 related codes
